There are many ways to interpret the question. I guess OP is promoting AI as the answer to the next “ big thing.” However, I interpret the question to mean “what comes after the Internet?” Several comments have suggested mobile as the next thing after the Internet, and I would tend to agree. You could also argue for social media platforms. So what comes after mobile? The core requirement for pictographs, writing, books, telegraphs, telephones, radios, television, the Internet and now mobile has been the need for communication. Humans need to be social and they need to communicate. I would think that the next thing after mobile will be some faster, more accurate, higher information density and/or convenient way to communicate. Put your thinking caps on and try to imagine a better communication scheme than we have right now.
