Since this conversation has focused on AI, I don't think my recent experience is too much of a thread drift. It was an interesting contrast in "bad" vs "good" AI.
Just as a lark, I typed "what is the correct cotter pin to use with an AN3 bolt?" into the google search line. As often happens with google searches, the first posting was an AI-generated summary paragraph. In it, it said that the correct cotter pin was a 3/32 diameter. Well, that is obviously wrong, since the drilled hole in an AN3 bolt is 0.070" diameter, so a 3/32 cotter pin would not fit. This test pretty much reinforced all my prejudices about AI.
I mentioned this story at our monthly poker game, and one of the other players mentioned Grok. He pulled out his phone, and we put it to the test. I asked Grok three questions, and it got all three right.
The first question was a repeat of the cotter pin question. Grok correctly said, "a 1/16 cotter pin such as a MS24665-132."
Wow! I was really impressed. Stunned, in fact.
Then I asked Grok what the correct mixing ratio was for Rhino 1307LV epoxy (the epoxy we most routinely use in our shop). Grok correctly replied, "use 4:1 by volume or 100:22" by weight." We use 100:23, but close enough. I'm even more impressed.
So lastly, I asked Grok, "What is the answer to life, the universe, and everything?" Grok wasted no time in coming right back with the correct answer, "42."
So, I don't know - clearly AI is getting better. I'm wondering when it will be good enough that auto-correct actually works on our phones.
