It would explain how we have the big 4, and not the big 94. Some like yahoo get carved up more publicly, but they all do in the end.

This is an overblown statement lacks substance.

If by technology company, it means doing their business through smart phone APP, then Uber is one. In this definition, this statement does not hold strongly.

If it means that the company build their business around proprietary technology that few can match, Uber is not yet. It's obviously that any decent technical group can deliver a comparable service as Uber with reasonable amount of VC money. The proof is that there are many such companies across globe.

Uber actually realized this, and is strategically focusing on self-driven car, which is no doubt a correct and necessary move.
