Not sure if you mean this literally, but I'd rather have a fellow developer who shows me an automated way to do (most of) this, meaning the devloper realized that switching to another machine would require figuring out and executing those same clicks again. It's like the discovery process you mention, but imo with deeper insight. Also because I've seen the other end of the 'oh I still need that thing let's point and click to install': co-workers needing multiple days to get their development environment setup. Or rather: thinking it's setup only to find out some days later the envoronment is so polluted only the correcct sequence of starting a shell and executing scripts leads to a build without errors.
