Are you allowed another tweeprint for a revised preprint? Anyways, it's been a year since we first put out PhysMAP (I also do [many] monkey experiments!) and thanks to some excellent reviews + additional co-authors, we're really excited about where we've landed! www.biorxiv.org/content/10.1...

It’s just so weird to read this because if you talk to any devs that use these tools, you get near unmitigated praise. I get 5x or more speed ups: ported my entire codebase into Python and built an app in 4 hours with Claude code. I’m convinced people who write this off just don’t know how to use it
“One notable MIT study found that 95 percent of companies that integrated AI saw zero meaningful growth in revenue. For coding tasks, one of AI’s most widely hyped applications, another study showed that programmers who used AI coding tools actually became slower at their jobs.”
