I don't think anyone considers AI to be something useless. It sure has its uses, I use it a lot to help with research. But it is sometimes shoehorned into things it doesn't belong, or its capabilities overblown for marketing. I think that's what people object to.
The S/N ratio entirely depends on whether you care about AI and I don't not really.
I meant I don't really care, I keep half an eye on what they are up to (have to live in the same world as them) but I'm not really interested in it at all beyond playing with some local models, the constant onslaught of it has just become tiresome, then I got to YT to watch my usual history content which mentions something I didn't know about so I do a search to see if there is a video on that and that is wall to wall AI slop and that annoys me so I go to do something else, do a search and the results are slop if the AI doesn't try and answer it for me first.
It just feels like if you want to do anything on-line you get force fed slop whether you want it or not and it's damn hard to filter it, can't even block channels on YT without an extension.
Edit: I'll also note that while its nice to see real novel AI news I find a lot of it is extremely marginal value. I mentally associate most discussion with debating what color of marker to use when marking the edge of your CDs to improve the sound.
Sadly this would not end just as a joke. We'll be doing this forever from now on.
