"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.
