One fun heuristic I've used for thought-experiments in futurology is to ask "what will be to cheap to charge for eventually, and what comes of that?" For example, electricity. Or water. Or fuel/energy for vehicles? Or computation? What would you do if you had unlimited internet bandwidth? What will have scarcity value when we can harvest asteroids for unlimited diamonds (or just... not stockpile them)?

There's the missing Step #2 problem, but it's still interesting to think through. And in my personal experience, it can also lead to you creating the future but too early for it to be truly viable. And that can 'waste' a lot of time, if you don't enjoy or value the the exploration in and of itself.
