I often code directly on the machine control, including single blocking a running program and adding a line while the program is paused.
Editor on older CNC machines usually doesn’t even do lowercase and often has limited alphabet keys. Think '80s green or amber screen.
A machinist’s coding workflow can be real fucky. I go from CAM which is like a highly complex visual programming IDE to notepad. If I’m being fancy I use notepad++ for syntax highlights and diff’ing.















It would require Von Neumann machines to do it. Of, course, we could end up being turned into grey goo with that sort of tech.
But, yeah, simply invent self-replicating nanotech. Shoot it at the moon, Mars, Ceres. Viola, data centers in space. Use the same tech to clean up the enviroment and eliminate oil dependence. Might as well rebuld the coral reefs and old growth forests. Also cures cancer and the common cold. And is the fountain of youth. And we all live happily ever after in the computer.
