Tech's broken promises: Streaming is now just as expensive and confusing as cable. Ubers cost as much as taxis. And the cloud is no longer cheap.

• The tech industry has been on a quest for profitability lately.
• To get there, some tech companies have been raising prices. 
• The result: Supposedly revolutionary services are looking a lot like what came before.

Sooner or later, everything old is new again.

We may be at this point in tech, where supposedly revolutionary products are becoming eerily similar to the previous offerings they were supposed to beat.
