LLMs aren’t a scam, I don’t even understand how you could twist it into such. While something like NFTs have no real legitimate use case, LLMs excel at translation and as an advanced form of spelling and grammar checking.
Your complaint seems to boil down to “it doesn’t work in all use cases it’s being used” which is fair enough, but if I put a car on my bed and try to use it as a blanket… does that make it a scam?
Have to use? No one has to use any library. It’s convenience, and in this case it’s literally so they don’t have to write code for older browser versions.
The issue here isn’t that anyone has to use it, it’s the way it was used that is the problem. Directly linking to the current version of the code hosted by a third party instead of hosting a copy yourself.
