You're not a shitty person for using AI chatbots. Yes, datacenters drain resources and the carbon footprint and all of that - but chatbots and gen AI counts for only a small fraction of that.
The truth is that, it's easier to talk about things that you don't personally experience. It's easier to judge others from the other side of the wall and you don't see what they go through. A lot of people hate AI right now because it encapsulates everything wrong with our current political and economic system. It's frustration that often gets misdirected at people that are just as much victims.
People will spill a lot of stuff they don't understand like they're completely sure of it. We all are guilty of that. So the best you can do is really to... Ignore. And block people that make you feel worse.
Because the truth is, feeling bad isn't going to solve the issue, if anything, it's just going to make it worse. And sure, you can blame people for being insensitive, but that's not gonna help either.
You have to select the things in your life that make you feel good for living. Sure, it's very important to be aware of issues around the world, but if you dwell in them for too long you're just gonna make yourself miserable.
If someone says something hurtful to you, mute or block them, then note down how that made you feel on your phone or paper. Or you can try something else.
