I am yet to see that ‘companies with great ideas which simply cannot afford those very expensive developers’. For the most, issue is not programmer costs. Mostly it’s inability to formulate the MVP which makes sense.

‘uber for my industry’ is not a sensible business strategy

Honestly, if you know guys whose bottleneck is pure software dev — please let me know, I have a good, experienced team in Eastern Europe, we can do wonders in product development. But coming up with sensible business ideas and executing on them in the real world is crazy hard and extremely rare.
