At the end of the day, Pepsi and Coca-Cola sells you sugar water. McDonald's and Burger King get the same meat form the same vendor trucks. You charge a credit card whether Visa or MasterCard.

Uber/Lyft has commoditized driving to a product sold at ~$2/mile. That's why this week they both launched loyalty programs, back to back.
And from there they'll just keep trying to add more value bit by bit. Not surprised at all if in 10 yrs Uber doesn't have cab hailing anymore, but you ended up on an Uber flight to Shanghai.
