I thought the quote in my comment have it context sorry. My point is that, as a lot of tech innovation has matured, the potential to do good has been lost as the big players, who burned investors cash to corner or create markets early on, squeeze everything for profit. Uber is a great example and the recently leaked emails show this was always the plan. Lighting would be more likely to go that way, cornered by a single company and squeezed to death.
