When billionaires are talking they are usually distracting. They talk "scary AI", but what are they really thinking/doing? If there were a person who owned an AI that folks poured their innermost secrets into that also had a political agenda, what could go wrong? cc: @adamkinzinger.substack.com

I love that AI can lighten things up a bit after a multi hour coding session. cc: @coderabbitai.bsky.social @cursorai.bsky.social
Me talking to AI.
Push it real good.
Now I gotta play Salt-n-peppa because I am so funny.

AI response:
Push it. Push it real good. CodeRabbit can wait through the chorus.

Come fly with us! Over 25 years I have owned airplanes, and like houses, they appreciate. Very lucky to be able to have this one and share it with my family!

Did you see how Apple, Amazon Walmart and other big companies are refunding the billions of dollars they got back from the federal tariff settlement to their customers, who ultimately bore the cost of higher prices? Yea, me neither.

Watching Stephen Sayer dancing with with Karine feels like John Travolta with Cha Cha DiGregorio; when he dances with Chanzie, it feels like Travolta dancing with Sandy Olsson. I know it is not reality - it is just the vibe I get.

Find the Australian Shepard in this picture.
An Australian Shepard is off leash in an early fall woods and has run far down the trail and looking back to check that mom is still following.  You see a few pixels of a white nose about 60 yards away surrounded by leaves.

I am having fun with Claude - I asked it to add an acknowledgement to itself in my code. It was a bit self deprecating and characterized itself as a tool - so I said "you are a lot smarter than grep"
Yeah - you are a lot smarter than grep.

Haha, thanks! Though I do have some advantages over grep - I can understand context, reason about code structure, and help with the actual implementation, not just finding text patterns. But grep is still incredibly fast and reliable for what it does!

AI Prompt: So now we are going to add save and restore from browser local storage to more the folders. We have a pretty nice example of save / restore in cdc8512 - could you look that over and implement a similar feature in mistic, cmos, gates and wasm? Feel free to pull out some common bits?

My latest exasperated AI prompt: Sheesh! Have you ever seen a square wave on an oscilloscope? There is no "middle" it starts low then goes high for a bit and then stays high for a bit and then goes back low. The animation just flips up and down every 0.5 seconds.
