In Drupal we can often get 2/3rds of our app for free, which productivity-wise has let us accomplish things in timeframes that would be impossible in Rails.
If something with Drupal's advantages were available within Rails (as an engine or what have you) it would be a clear game-over for other stacks vs. Rails.
Should brains like this have any desires that conflict with our needs, we will be in an extraordinary amount of trouble.
I'd be uncomfortable using formlabs type resin parts for anything with load or wear, using them within machines, joints for a table, replacements for dishwasher parts, etc. I can't print anything of size with formlabs type printers. If I want to make a quadcopter body, or a modern-art lamp, I'm SOL. You have valid points--just are valuing use-cases differently than I do.
Most of the fused deposition printers (like the MendelMax, AO-100, reprap Prusa (2 and 3) can print in more materials (ABS, PLA, even Polycarbonate), and produce larger functional parts than things like FormLabs. The main issue is the striping, which is less "pretty."
