My mind is blown, a new language where I can see new reach. Back in the day, APL was good at multidimensional arrays, and from there could outstrip Fortran shops at anything. A surprising swath of discrete reality can be viewed as a graph, or graphs of graphs. For me, computational group theory, combinatorial enumeration, canonical forms... All topics Claude 3.5 Sonnet happens to be exceptional at.

Even a month ago, I'd have asked "Where's the parallelism?" looking at any new language. AI has upended my world. My subscriptions are getting out of hand, they're starting to look like some peoples' sports channel cable bills. I'll be experimenting with the right specification prompt to get AI to write correct programs in three languages side by side, in either Cursor or Windsurf. Then ask it to write a better prompt, and go test that in the other editor. I'm not sleeping much, it's like buying my first Mac.

One constant debate I have with Claude is how much the choice of language affects AI reasoning ability. There's training corpus, but AI is even more appreciative of high level reasoning constructs than we are. AI doesn't need our idioms; when it taught itself the game Go it came up with its own.

So human documentation is nice, but who programs that way anymore? Where's the specification prompt that suffices for Claude to code whatever we want in Dusa?
