I would guess that the continued success of Rust have shown that we don’t have to live with the user-hostility of C in order to write system programs. Therefore, people are understandably growing less and less patient with C and its unending bullshit.

Although I haven’t noticed a spike the last 6 months, just a slowly increasing realization that C isn’t fit for humans and should go the way of asbest: Don’t use it for anything new, and remove it where it already exists, unless doing so would be too expensive or disruptive.

I don't think C is hostile. C has UB for good reason. The problem is UB has been hijacked by the compiler writers for performance gains.

Personally I like C because you should have a good idea of what it's going to do. Other languages feel like a black box, and I start having to fight them far too often. But I say that as a hacker of low level stuff, not as someone who's paid and working on higher level stuff, so that is probably a niche view.
