Everyone has one at home spitting out items they need daily/weekly like was promised. I don't know if you remember the 3D printer (somewhat) boom of the 2010's but the hype was crazy when it became more mainstream. Maker spaces popping up in cities everywhere, schools showing off their units, every conference had some talk on them, startups left and right. The AI boom is basically a more-funded version of that. It was hot hot hot and people thought every home was bound to have one.
It took a while, especially because the early 3D printers were a project of calibration unto themselves, but modern printers are fairly trouble free. I accidentally melted the bottom of my blender jug on my toaster oven so I'm printing a replacement one right now. Turns out the critical mass needed is someone else having already done the CAD so I can just hit print from my phone, which makes 3D printing a reality.
