Incentive is social praise, respect of your neighbors and personal fulfillment knowing you have a needed skill. When all you're other needs are met, it could be enough.

I think the main problem here is that a few in this that are thinking 1:1 replacement - I'm not saying the Apple store is going to be fully functional, I'm saying I've known and worked with a lot of great engineers that like to solve problems, almost compulsively. If society made sure "the rest was taken care of" so they could do what they did best, they'd put in solid work week each week, help train others, etc.

Also, too many of you are caught up on the 40 hour work week. It's not needed and in a better structure you'd work less often. I'm realistic, the world won't get there on my lifetime or maybe ever, but it could work.

This whole detailed dive into silicon aspect specifically is a strawman though, that's not the point of the discussion.
