If you've only been using AI for a couple of weeks, that's quite likely a factor. AI services have been improving incredibly quickly, and many people have a bad impression of the whole field from a time when it was super promising, but basically unusable. I was pretty dismissive until a couple of months ago, myself.

I think the other reason people are hostile to the field is that they're scared it's going to make them economically redundant, because a tsunami of cheap, skilled labor is now towering over us. It's loss-aversion bias, basically. Many people are more focused on that risk than on the amazing things we're able to do with all that labor.
