Many of us are worried. Hell, I was publicly recognized for the depth I went into around the product you likely know and may even hate. I wrote books on it. I dove into and debugged it's closed source code. Etc. I don't want to touch it again. In fact, I'd rather go into environmental science so I can contribute something to the greater world. But that would require schooling and that doesn't seem to be desirable in your 40s. Not that it can't be done, but it would be an enormous pay cut plus student loans. Anyway, find something that makes you happy. Don't chase the tech. Like other's have said, blockchain was "hot", crypto was "hot", data science may be reaching the tail end of it's "hotness". I expect AI in today's form to fizzle out, as well (can't speak for it's future states). CEOs/CIOs/CTOs rah-rah this shit and time and time again we're back to doing generalists work - Azure/AWS/GCP web services, some API middle layer, some database layer. And that's okay!
