I reckon that some people are either critical of LLMs due to the data that they're trained on (concerns about the legality of using the outputs, or the ethics of taking open source projects with a variety of licenses and how transformative or not the output might be), or question the quality of the code that they might output. Oh, also there's hype cycles and right now people at large might overestimate the capabilities of what LLMs can or cannot do well, which can be tiring, as seeing constant posts about crypto was (where we had a solution in search of a problem).
In my eyes, they can be used in conjunction with something like IntelliSense and IDEs to solve select problems (ones with solutions that already exist out there) more quickly, as well as save time on some boilerplate, as long as you still validate the outputs and actually check if everything works. Nowadays I'm using GitHub Copilot and the user experience is mostly okay, I'd say it actually lets me write code faster, at the expense of occasionally getting things pretty wrong, but is still a net positive, other considerations aside.
