And the "magical" part is not really for devs who have their dev env setup. For them it's an "oh so what" moment.
It's for: - New joiners - Non-engineers - Devs contributing to codebases they have not set up locally (and now no longer need to setup locally!)
Two weeks ago, I talked with a startup that built the same thing for themselves: a cloud dev environment spun up via a Slack mention, anytime, and they said the same: that it was *absolutely* game changer for them. Because it's now so trivial to prompt work, incl parallel work.
And it's "magical" thanks to being hooked up to every internal system.
