"it is now popular to just have someone else do it...be it AI or a factory in another country"
And sure there are some people interested in reprap but they have been scattered to the wind. #reprap IRC has become an advertising/support channel for commercial printers. If you go to most of the channels/forums where the development used to happen and mention you want to build a printer you will be flooded with responses about how stupid that is and provided with names/links of the printers you should be buying. Making things is a fool's errand.
Maybe my observations were different...maybe not...but from what I saw at about 2016 the whole DIY machine thing switched.
If, however, you want to learn how to build one, or just have an experience of building your own tool you'll use to create stuff, it is most definitely not stupid to do it.
With 3D printing becoming mainstream, you'll have fewer people in those communities who support and live that approach though, and you'll need to look harder to find documentation and like-minded people.
Filled with socks and bots. No room for development.
2011 #reprap @freenode is long gone unfortunately. Glad to have experienced it.
GOOD! Those old DIY machines were awful. Even back then I wanted a printer that just worked, instead of spending hours just to get it printing somewhat accurately. I still have tubs of old ramps/smoothieboards/V6s and similar junk from that era, it was an awful experience. My X1C just works, I've printed more with it since I've bought it than all the other printers I owned combined. Sure there is still the occasional failure, but that is nothing compared to the failure rates I had before.
