How to get new ideas
Most things are strange, missing, broken for mundane reasons that you can't do much about. The space of new ideas is huge, but almost all new ideas are bad. One strategy I really like is to think of technologies you couldn't build 5 years ago but are just barely possible today. That's where yesterday's bad ideas become today's good ideas.
For example, laptops and phones produced 20 years of incremental improvements in li-ion batteries, and suddenly electric cars are "unlocked".
