Production line (which is not synonymous with automation) is suspected to be the transitional stage until we can make everything customized for cheap. (See developments such as in 3D printing, of so many things. We cannot 3d print microchip fabs or high vacuum tech... yet.) Then it's the design where a bit more time is required. Given sufficient development artisanship and variety in design would be the actual rule.

I raise you decentralized/federated democratic resource control.

A bunch of items can be also made from interesting abundant materials, ultimately making them available is the challenge. (Gimme that glass and carbon nanotube 3D printer. And a home EUV lithography machine. We can already make a sputtering chamber almost on the cheap...)

Anything else you want to add before you prematurely condemn technology?
