This goes for IDEs, programming languages, frameworks, etc. Think of a language like PHP, which made it so easy to code that countless shitty websites were made, ridden with spaghetti code and security issues. But, I was amongst probably tens of thousands of script kiddies who cut our teeth on PHP and eventually learned how to "properly" build web products. My first startup's MVP was a giant functions.php file and a bunch of templates, FTP'd onto a VPS. Probably wouldn't have gotten into it if instead I had needed to learn something like C++ or Java.
Yes, making something easier to do decreases the quality on average. But even skilled professionals can benefit from better accessibility. And it's hard to quantify the full benefit to those who wouldn't have been able to do the work without the lower barrier.
Personally, yes, I know if I blindly use Github Copilot I'll prob write some shitty code. But it just makes everything easier/faster to do. So I use it and put in a tiny bit of extra effort to make sure I'm not abusing it. And it's game-changing. I'm also sure tools like Copilot will improve at a pace that is much faster than people expect. It will recognize deprecated calls, misused calls, errors, security holes, etc.
