maintenance will be passe? Who is going to do the maintenance on any equipment or machinery or even his solar panels when needed? Who will grow food, transport the food to his grocery store? We could go on and on; who is going to do the work of maintaining the infrastructure of his life in this utopian world of his?
The solar panel issue is interesting. Besides other possible maintenance, the collection surface has to be kept reasonably clean or efficiency plummets.
That’s a lot of glass to keep clean.
