Do you think that that gets whittled down over time? At some point, I mean, if you go sort of maximally extremist on some of this agent stuff, it's like, oh, well, if you just instrument your app to look at the frame rate, it will know that the frame rate dipped and it can go bang its head against the wall, but Who cares if it bangs its head against the wall as long as you're not doing it to find that it was, you know, the main thread contention.

Things that are verifiable, like numerically, right, without a whole lot of unintended consequences, you know, in pursuing that numeric target, right? Those have been around for a while, right? Like WebKit famously, like the reason that Safari was so fucking fast was that team said, like, you know, CI fails if you if your check in makes it slower.

And these kinds of loops, because the relentlessness of agents with sufficient tokens behind them makes it really, really appealing whenever you can find those particular rungs to hang your hat on.

One thing that's way different, just like to take an example of like how these are improving so quickly.

In the 27 series of Apple releases, they replaced the old simulator.app with a new app called Device Hub.

Device Hub lets you much more cheaply spin up lots and lots of simulators.

It also allows you to have like a screen mirroring session with real hardware that's like plugged in or on the network so it can control your real hardware too.
