That’s almost never a thing with remakes. Counter-Strike 2 replacing Counter-Strike: Global Offensive is the one that would be most recent and is probably why you’re saying this. If not, you’re probably thinking of similar such soft relaunches after large updates (which arguably applies here, though the change is so substantial that they really shouldn’t have outright replaced CS:GO).
That’s a completely separate issue and should realistically have no bearing on whether or not remakes should be made. You should focus your anger at the true problem, which is that Games as a Service is fraud. Don’t let them entangle your feelings on this such that you accept things like a remake replacing an original game as not only normal, but also an inevitability.
There’s a distinction between intelligence and sentience.
The stuff impressing people right now only has a tiny short term memory and no way of really transferring that short term memory to long term memory, so it’s definitely not something you can characterise as sentience.
It is definitely intelligence, though, since it can draw from a very large pretrained set of knowledge with deep relational connections.
