If your internet died you would likely be worse at programming that you were in 2020. I think is what people are getting at.
If my internet died in 2020 I would also be useless because probably I couldn't install/download all the libs/frameworks, etc.
But if I didn't need those things, and there was a simple pseudolang syntax which acted exactly the same in all versions, didn't have any breaking changes, I would argue I'd be much better at it now.
Internet, search etc is needed to understand how to setup libs/frameworks/APIs, but logic at itself isn't something that I could possibly forget. AI will help to get those setups quicker without me having to search, but arguably it's all useless information, that will get out of date, that I really don't even need to know. I don't need to know top of my head what the perfect modern tsconfig setup should look like or what is the best monorepo framework and how to set it up, so it would scalably support all different coding languages for different purposes.
I always compare AI programming to Google. If that's the case, then without internet, without Google, without Stack Overflow, my abilities would be worse than they were in 2000.
