Agree. For me personally, 3d printing has been a "hit" and the printers keep getting better, cheaper and more reliable. Good bed levelling, multi-head, failure detection etc are reaching the mainstream and the printers I have now are amazingly better than what I started with. But most people (reasonably) don't seem that interested in making small plastic things. It's a niche thing to want to do and as you point out, there's a learning curve. Plus materials and process limitations mean that a printed item will generally be inferior to a bought one unless you designed it yourself to meet your exact use-case.
