I wouldn't say specialist, because GPT often ignores full context of the information. Sometimes, if a system is composed of A B C D E, and you only mention the first 4, it will answer with no problem as if E was irrelevant. As soon as you introduce E, then, it will quickly say sorry and reconsider. I'm a true hardcore generalist, and gpt can help a lot, but I wouldn't say I can become a specialist with it because it doesn't investigate at all - if you don't mention it, a lot of times it's as if it doesn't even exist.
As a technical generalist I certainly find myself pretty empowered by these LLMs. It's never been easier to dive into a new problem, figure out the boundaries and solution paths and get cracking.
