Wozniak had this great insight. It's like lathe. Everyone knows a guy who has one, but no one is actually bothered to get one. It's a nice thing to have in your workshop, but also requires lots of skill.
I disagree. I think it's more like how microwaves were in the 50s. Some people have probably heard of them, but are still suspicious of their usefulness...
And then one day everyone has one, and you can buy them at your local appliance store.
But microwaves solve a problem people have several times a day (low-labor way to get some hot food or drink). I'm having trouble envisioning a world in which an average person needs or wants a new 3d-printed object on a daily basis, even if it were completely free.
