While I agree 100%, I think the answer is more satisfying when viewed a different perspective. It's not that Uber needs all those engineers. It's just a question of marginal cost vs marginal return. Uber made 1.5 billion in revenue in 2015. An engineer costs roughly $150k / yr. An additional 100 engineers only have to make enough small improvements to increase revenue by 1% to pay for themselves.
