1 Introduction

Today, advanced digital technologies have been grooming worldwide with the speed of light. In contrast, industries and businesses face lots of trouble embracing advanced technologies to teach their changing behavior. Industries have to work with the speed of light to get their momentum, to conquer with these advanced high-speed technologies. These transformations can quickly be adopted by moderating or the agile mindset of industries. Digitalization in technology is the voyage, not a terminus; it supports the business models, medical system, manufacturing industries, etc., for their growth and shapes business and benefits customers. Now, all are at the hinge point where things are changing exponentially changing from mechanization to electrification to electronification to computation to mass customization to mass personalization to virtualization to digitization to intelligization to robotization to mobilization [1]. Nowadays, researchers are starting to think beyond industry 5.0, industry 6.0, a futuristic idea. Industry 6.0 is the idea, which varies according to the need of industries. Sometimes it is ubiquitous, customer-driven, human-centric, anti-fragile manufacturing, virtualized, human co robot centric and homogeneous assets, etc. The future prediction for industry 6.0 is to hyper-connect the industries to industries, highly mass customization, highly mass personalization of services and products with the attachment of dynamic supply chain management concept, highly customized class one lot size thinking where all the information can drift all across the countries.

The spread of coronavirus has broken the economic backbone of all countries and left its instances for many years. This worldwide crisis has compelled industrialists and service providers, medical, non-medical, and policymakers, to rethink how to manufacture the products and provide customer services. Presently, customers' behavior and necessities are shifting vividly because of this, and it raises the various challenges for manufacturing industries regarding providing services to them according to their demands, Since the customers are looking for mass personalization of products and services rather than mass customization in every field such as medical services and manufacturing services.

To deliver the first discussion over industry 6.0, authors tried to glimpse industry 6.0, its transformation journey from industry 1.0 to industry 6.0, vision and objectives, need of industry 6.0, supporting techniques, benefits, and challenges. Firstly, the authors present the inspiration behind the evolution of industry 6.0 from the industry perspective. Then elaborate on the futuristic idea behind industry 6.0 and its transformation from industry 1.0 to industry 6.0.

In conclusion, the authors finally climax the benefits and challenges in adopting industry 6.0 for industries.

2 Meaning of Industry 6.0

Industry 6.0 is the convergence of various ideas, which generates in the millions of minds of leaders, scientists, predicators, and researchers. Industry 6.0 is the one-step further than industry 4.0 and industry 5.0, where every operation would be controlled by human minds and performed by automated robots by covering all the planetary boundaries. It combines human intelligence, artificial intelligence, cloud computing energy, human–robot working big data, quantum computing [2], etc. It is a futuristic idea, where various manufacturing operations and services are provided to customers using artificial intelligence, cloud computing energy, human–robot working, big data, where satellite and industrial AI (Artificial intelligence) enabled robots would assist [3]. It is the amalgamation of sustainability, anti-fragile goals, and digitization, which could significantly help the medical system and manufacturing industries, and it would take approximately 10 to 15 years to implement. This revolution focuses on providing virtualized antifragile manufacturing and anti-fragile services focused on customer-centric, customer-focused ethos, super-connected industries with vibrant supply chain, automated flexibility, internal value networks where proper interactions within the organization or outside across the various nations and its administrative areas. This revolution would boost quantum computing [2] for solving the complex and colossal massive algorithms of present AI models and Machine learning techniques and open the door of opportunities for novel programming and AI algorithms, making human work more accessible and practical [4].

3 The Vision of Industry 6.0 Toward Sustainability

Industry 6.0 is looking like a futuristic industry, where its vision is far broader than the remaining industrial revolutions, which held up till now. This revolution will work to influence the industries 6.0 toward changing the work culture of humans, with the use of noble creativity of human beings associated with machines and advanced production systems in the highly cutting-edge digital technologies environment [4]. In this environment, humans can directly operate the machines using brainpower, which would be enabled with digital technologies and perceived resource competent and user-oriented manufacturing solutions compared to other industrial revolutions. The future industry 6.0 focuses on sustainability, homogeneous assets, safety, resilience, Antifragility, harmony with nature, co-working use of technologies (digital twins), and eco economy [4,5,6]. Industry 4.0 and industry 5.0 consist of promising cutting-edge technologies and applications expected to assist the futuristic industry 6.0. Figure 1.

4 Transformation Journey from Industry 1.0 to Industry 6.0

Earlier, many industrial revolutions have occurred so far, and these comprise of industrial revolution 1 (I.1), industrial revolution 2 (I.2), industrial revolution 3 (I.3), industrial revolution 4 (I.4), and newly introduced industrial revolution 5 (I.5). Figure 2 demonstrates the transformation journey of industrial revolution 1 to industrial revolution 6 (Futuristic Idea). The first industrial revolution came into existence from late 1784 to 1800, where the mechanized production system was introduced, the first mechanical loom. In this revolution, mechanical machines were introduced in the industries, which has reduced the workload of humans. The second industrial revolution brought the division of work, mass production, and electrical energy to run the machines in 1870. Industry revolution 3.0 came into the light in 1969, brought advanced computer technology, Information and Technology systems, and automated production, which enhanced the productivity of industries. After that, a new revolution era started in 2011, i.e., industry 4.0. This revolution has brought recent changes in the entire manufacturing market. This revolution reformed manufacturing and communication channels with customers to fulfill their requirements. This revolution develops new digitized trends for the market comprised of new technologies such as the Internet of Things, 3D printing technology, Robotics, Big data, Cloud computing, and many more. In addition, many researchers, scientists, leaders, and scholars have also started to think about industry 5.0 [4, 5]. Industry 5.0 is an emerging field that lies in the concept of human co-working with AI-enabled robots [4, 6]. This revolution works for the mass personalization of products rather than mass customization.

Industry 5.0 consists of two far visions, wherein first vision focuses on the culture of humans working with robots, development of smart societies, use of the renewable supply of power or sources, development of the smart and safe environment, new innovative ideas, research, developed smart administration work enabled with digital technologies. The second future vision of industry 5.0 is to bring bio-economy, sustainability, bionics, preventing wastage, digitalization, new innovative ideas research, and developed smart administration work [4]. In addition, industries have started to think about industry 6.0, which is one step ahead of the fifth revolution. Industry 6.0 is a futuristic concept that industries will implement approximately 10 to 15 years later. This revolution focuses on providing service takers with virtualized antifragile manufacturing and antifragile services. It would focus on customer-centric, customer-focused ethos, super-connected industries with vibrant supply chains, automated flexibility, and internal value networks—the proper interactions within the organization or organization across the various nations and its administrative areas. Table 1 shows the glimpse of comparison among industry 1.0 to industry 6.0 by its sole objective of various industrial revolutions, impetus, resources used, technologies used, and emerging research trends.

5 Research Objective of Present Work

Industry 6.0 is a futuristic concept; if it applies to industries, it will change the entire scenario of the manufacturing world. The sole aim of industry 6.0 is to seizure the new technologies, which can be applied worldwide and deliver wealth, prosperity away from the job and growth to nation across all planetary boundaries and keep a man in the center and machines around him. Industry 6.0 is the compliments to future industry 5.0. This revolution would bring flexibility in the manufacturing world highly as per the requirement of customers, stakeholders, shareholders, organizations with the help of various digital technologies, quantum computing, automatic robotic industries, which would be controlled by quantum radar, quantum electricity, cloud electricity, planet thermal energy, etc. This paper revolves around some research questions.

  • Question 1 To study the need for industry 6.0.

  • Question 2 To find out the techniques which can support industry 6.0

  • Question 3 To study advantages and challenges of industry 6.0

6 Need of Industry 6.0

In the present era of COVID-19, the entire world was facing difficulties meeting customers' demand regarding supplying goods services, manufacturing, and other daily need items. This global crisis has forced manufacturers, organizations, and service providers to rethink the current production strategy, delivering services to customers, customer interaction, supply chain network, circular economy, integration of products, green transition, and digitalization. Throughout the industrial revolution history, it has been seen that industries have the caliber and proven their capability to the prime transformation. In addition, enterprises will always be ready to accept this transformation toward the weather change impartiality and change in digital governance in a flexible and foreseeable world. This revolution would eternally connect the planet affected by weather change and ecosystem calamities, so there are some counsels to reduce the risk of exposure against the global threat in the forthcoming time. If all desire to be ready for future shudders, all must emphasize robustness, safety, sustainability, resilience, and antifragility concepts. This revolution would bring novel ideas and innovative technologies that would craft new growth and welfare for humanity [11, 12].

7 Supporting Techniques for Industry 4.0 to 6.0

It has to be speculated that the past industrial revolutions were based on mass production, automation, personalized customer demands, and substantial production runs where machines are engaged with humans and enabled with AI algorithms to manufacture the products and provide services to customers their requirements. 3D printing technology is spreading its wings toward a new degree of freedom in the new revolution by adding a more comprehensive range of materials, biomaterials, chemicals for lithography control release medicine [13]. These 3D printed, AI, machine learning-enabled technology used in medicine could reduce the chances of infections during the human touch in OPD services. In the present time of pandemic where daily new viruses are ready to attack humanity, these robotics-based medical systems could ensure the safety of humans with less risk [14]. In 2005, Mitsubishi (wakamaru) imagined the dream of home front assisting robots, now in the sixth industrial revolution, it is the postulate that would assist aging people [15]. For the EEG, this would provide a significant advancement to humans where it would have the potential to add simulated pain receptors, which would tend to fix natural skin on body parts by using synthetic or artificial materials [16]. Quantum computing can transform the shape of business, industries, healthcare systems, finance, and material science by solving complex problems that traditional computers cannot solve [17]. Quantum computing has great potential to change the supply chain, value chain and expand AI. Industry 6.0 is the amalgamation of industry 4.0 and industry 5.0 with innovative convergence ideas. In industry 6.0, humans, robots, advanced technologies, quantum computing, antifragile manufacturing, digital twins, dynamic supply chain concept, multidimensional printing technique, home assisting robots, robot-based medics and deep plunge electroencephalogram (EEG), etc., would work together to make human work more accessible and provide zero defects services to customers. These technologies would enhance human capabilities and skills in manufacturing and other areas by providing them significant opportunities to learn and assess in the R D. Figure 3 and Table 2 shows the key assisting technologies in evolving from industry 4.0 to industry 6.0 [1].

8 Benefits of Industry 6.0

Industry 6.0 would support hyper-connected industries, provide dynamic value networks, dynamic supply chain, transparency in information flow all over the administrations either internally or externally throughout the world. It would be the way of life with keeping the proper balance or mastering the economics of learnings. It promotes the human virtual digital twin where all can simultaneously see physical goods and virtual product information, connect the manufacturing industries globally, and provide superior technical help, better understanding, and decision-making. Antifragile manufacturing will be the predicted concept for this revolution, where antifragility can be obtained through systems flexible design. It depends on non-functional requirements where software systems are judged based on openness, usability, safety, movability, and other functions that create hurdles in attaining a software system [36]. In the coming years, this revolution would provide creative thinking, unique and innovative ideas in manufacturing and other fields and enhance the protagonist characteristics of humans and machines.

9 Limitations of Industry 5.0 and Assisting Technologies of Industry 6.0

Industry 4.0 was based on mass production and smart production, whereas achieving sustainability resilience [37] and collaborations of man and machine [38]. It was the concept of industry 5.0 [4], and the futuristic concept of industry 6.0 advocates antifragile manufacturing, ubiquitous, human digital twin and customer that connects manufacturing, hyper-connected industries and customer needs are on high priority with use of sustainable resources. For a few years only, researchers, industrialists, policymakers, and future visionaries started to think beyond industry 4.0 and industry 5.0. Additionally, some futuristic have also pointed out the inadequacy of both industries. According to the view of Johansson et al. that industry 4.0 may have a low tendency to integrate digital connectivity and man–machine alliance [38]. It had already well known that artificial intelligence and robotics engineering is one of the essential supporting columns in the fourth industrial revolution, only the primer of the machine and human collaboration is not enough to start the new revolution. According to the Hirsch-Kreinsen et al. [39], the cost for implementing digital technologies such as IoT, AI, big data, and robotics in the industrial revolution 4.0 and industrial revolution 5.0 has required a large amount of cost and extraordinary skill, which could be the reason of un-satisfaction amongst the industries and social perspective. Industry 5.0 represents some exclusive limitations and responses such as high price responsibilities in manufacturing policies, standardization, and legalization in all policies to preclude any thoughtful problem among the digital technology, society perspective, and business [40]. The probabilities of social heterogeneity among the society in relations of values and adapting the new technologies of a new revolution, measurement of ecological balance and social values, significant investment and integration of all the customers from high business to SMEs, and environment based new policies with agility, outcome-based [41], and greater dependency on technologies [42]. As a noble initiative by business, Finland in “From industry X to industry 6.0” was sketched a series of predictive implementation strategies, policies, investment, business landscape, Research and development, and manufacturing ecosystem and future path dimensions to promote industry 6.0 [1]. Additionally, government, agencies, and industries responses are being limited for some time. Still, academia is peerlessly embracing the critical discussion on industry 6.0, as MDPI journals, Journal of manufacturing systems, World Conference on Technology, Innovation and Entrepreneurship, and IET (The institution of engineering and technology).

10 Challenges in Implementing Industry 6.0

The dream of industrial revolution 6.0 can only be attained by doing systematic work and collaborative effort of government and manufacturers toward the welfare of society. This revolution wants the long-term commitment from the manufacturers, policymakers, stakeholders, and government to implement sustainable industry 6.0 in the organization. The implementation of this holistic approach can be geared with proper research and development to positioning in the revitalization of Industrial Production. During the execution of industry 6.0 could face many challenges such as digital transformation, difficulty in adopting new and advanced technologies, allocation of resources, industry-relevant technology, internationalization, industry collaboration, freedom to research in development, capital cost (needed funding) involved in developing and implementation of new technologies, reskilling costs and adoption of 5G /6G technologies.

11 Conclusions

Industry 6.0 has been the theoretical concept; it will change the manufacturing world's entire scenario if it applies to industries. Numerous people have been scared of losing their jobs due to complete automation in industries, so it is required while introducing any new industrial revolution that the number of jobs should always be more than the job loss. Otherwise, social un-satisfaction and negative impressions could engender in society. This revolution focuses on providing virtualized antifragile manufacturing and antifragile services. It would concentrate on customer-centric, customer-focused ethos, super-connected industries with vibrant supply chain, automated flexibility, internal value networks where proper interactions within the organization or outside across the various nations and its administrative areas.
