'almost all ideas are bad' This is not the way to look at it. 'Ideas' are too early to be judged as good or bad. Ideas are fodder, they are there to be moulded into things that are good or bad. Often ideas are just foils to help you think. They are so contextual as well: 'full screen smartphone' was maybe only possible by Jobs, with that much direct and coercive power over engineers. Motorola CEO was not going to pull it off. But Apple did work with motorola to make a 'music phone' as an experiment. I think your note about 'yesterday's ideas' is bang on.
