Do you mean that in the sense that healthcare tech has been slow to move in terms of making advanced bionics available to the public that needs them? My general impression would make me agree, although bionic prosthetics have gotten way better in recent years. Simultaneously, it all seems like tech that could have been available decades prior.
1) Incredibly expensive, but if you have insurance that pays for it, amazing. 2) DIY hobby projects that are "good enough" to still have incredibly profound impacts on peoples' lives. They aren't particularly costly, but only available if you're lucky enough to know someone with those skills.
I know it's not a trivial problem, but it seems like we should be able to mass-produce the "good enough" version and make them widely available at an accessible cost.
Having a working prototype with a technician on hand means you’re only about 10% of the way to having a mass-producible product though
