What frontier models also excel at is writing their own libraries and skipping third-party dependencies. It's very easy for a human to just pick up a bloated 750kb library they're only going to actually use 15kb worth of its code for, BUT that library can serve as a valuable implementation model for someone very patient and willing to "reinvent the wheel" a little bit, which is definitely going to be AI and not me, because I just want to point to a black box and tell it what to do. For big things like web server, I'm still defaulting to Axum, but for things like making a JS soundbank parser/player or a WebGL2 mp4 & webm parser/demuxer & player, these are tasks frontier models are good for with the right prompting.
To an extent, maybe counter-intuitively, I think the big thing we'll see out of AI is an explosion of artisanship -- with humanoid robots in 2040, perhaps, our households may be making their own butter again, for example.
I know part of it is that sales wants to be able to price discriminate and wants to be able to use their sales skills on a customer, but I am never going to sign up for anything that makes me talk to someone before I can buy.
Anyway, long story short: I now require the price and details before I'll even consider talking to a salesperson, not the other way around. Might actually be a good job for an AI agent; they can talk to these sales bozos (respectfully) for me.
