I've done terminal strip with point-to-point wiring chassis builds, dead bug/spider web, wire wrapping with perfboard and of course homebrew etched PCBs using strip tape but never have I had to do any of these crazy methods of circuit assembly. That glass substrate method is wild. I can't imagine trying to do that in DIY as an electronics hobbyist. It really would have made the home game a lot more difficult. So glad we've come a long way from those days.
I found it amazing how we initially approached printed circuits in those early days, crude but effective ... and manually intensive, fraught with opportunity for human error. This was their process ~30 years before I became involved with printed circuits (in semiconductor test and characterization). By the time I left the semiconductor industry, we were designing complex 30-40 layer probe cards and load boards, CAD drawn onsite, files sent off to the card vendor, new boards of the highest quality shipped and received in under 2 weeks for relatively cheap money. We've come a long, long way.
