I feel that as a field, we overfitted towards economic value maximization (which, to be fair, is the obvious thing to do) while leaving important problems behind.
Accessibility, sanitary infrastructure (in developing countries), generally improving health (including making it cheaper), and environment/wildlife preservation being some good examples of largely unsolved problems that technology still holds the key to dramatic improvement.
This might be the right time to start working on these things. Ironically, warfare, advertisement, and wealth concentration helped advance technology rapidly, making it easier to tackle other problems.
