the idea that uber loses money on rides because of "VC" needs to die. uber is not VC funded anymore and hasn't been for a long time now.

uber loses money on every ride because uber loses money overall because it spends a lot of money on other projects, not because the marginal cost/benefit of each ride is negative.

If they spin off the ride sharing part of the company how much are they earning? do you know?

The ridesharing line of business has been profitable for at least a year from what I can tell. The plan was for it to cover all the other costs by EoY 2020, incl. HQ expenses and other bets like Eats.

Centuries ago, people got by with horses. Does that mean that cars aren't essential?

Ridesharing services allow for an unprecedented level of mobility for those who don't already own cars.

You could say the same for taxis. If uber cost 100$/ride you wouldn't be claiming it is unprecedented. It will die because no one wants to pay for it with the real cost: livable wage + proper car insurance.
