I don't think the analogy works.

3D printers are still fiddly, require a lot of know-how, take up space at home, resin printers often use toxic materials, and are generally something for which you need specialized equipment, supplies, and knowledge.

Comparatively, the latest LLM models are much easier to use without specialized knowledge, take up no space in your house, and give decent/good results. Again, not entirely there yet, but this is moving faster than 3D printing tech.
