Anyone interested in STEM/STEAM spaces and equipment should watch this video. It is older, but worth a revisit. He says we need 20 years to make this feasible and affordable. I think we might be moving a bit faster. He compares the evolution of Fablabs (and personal fabrication) to the original development of UNIX which was done on a PDP-7.
I think the most interesting aspect is we can “go back in time” with his prediction, look at the current state of development, and confirm what direction the technology and pricing are heading.
