I feel hobbies are just the early research phase of future technology. It’s starts as a diy, people invent iteratively on the idea, bringing new theories and solutions until a company takes all those patchworks ideas and turns them into a working product. Bambi seems like the first company to present a decent turnkey finished solution taking all its ideas from the DIY scene. Yea there is Ender and Prusa but they still need all that learning.
