Senior developer here. It is hard to overstate just how useful AI has been for me.
It's like having a junior programmer on standby that I can send small tasks to--and just like the junior developer I have to review it and send it back with a clarification or comment about something that needs to be corrected. The difference is instead of making a ticket for a junior dev and waiting 3 days for it to come back, just to need corrections and wait another 3 days--I get it back in seconds.
Like most things, it's not as bad as some people say, and it's not the miracle others say.
This current generation was such a leap forward from previous AI's in terms of usefulness, that I think a lot of people were looking to the future with that current rate of gains--which can be scary. But it turns out that's not what happened. We got a big leap and now are back at a plateau again. Which honestly is a good thing, I think. This gives the world time to slowly adjust.
As far as similarities with crypto. Like crypto there are some ventures out there just slapping the word AI on something and calling it novel. This didn't work for crypto and likely won't work for AI. But unlike crypto there is actually real value being derived from AI right now, not some wild claims of a blockchain is the right DB for everything--which it was obviously not, and most people could see that, but hey investors are spending money so lets get some of it kind of mentality.
I had always thought this is where the term "bug" came from, but the log says "First actual case of bug being found", which to me implies misperforming routines were called bugs prior to the "bug" being found.
