I mean they're researchers, not builders. If this all checks out, they've done their part and this should inspire builders to run with it and commercialize or open source a printable design. Specialization is great, glad someone is focused on continually pushing the research and improving the designs, and this one supposedly improves on last year's design. There are others who are better at scaling & commercializing, and those types are probably a lot worse at basic research. Every inventor and researcher doesn't need to start a startup.
