Uber Freezes Hiring of U.S. Tech Staff as It Seeks to Cut Costs

Do you really believe that Uber is run on a technology stack that is 40-50 years old?

Of course not, but I do believe - because it’s demonstrably true - that those challenges are not unique to Uber, and that they have been solved many, many times over.

For example sure, Uber handles a lot of trips. But every one of those trips is backed by a credit card processor, without the latter even breaking a sweat. I guarantee that Mastercard or whoever barely even notices the additional workload they get from Uber.

You’re correct, the transactional part is true, but MasterCard is following a relatively basic process:

1. Authenticate the transaction (is this ‘uber’ Company ok and is it reasonable this user is using it for fraud detection)

2. Check that the users balance + the cost of the trip < the users credit limit

3. Post the change to a transaction log

4. Some hours/days later, finalize the pending transactions.

That’s a whole lot simpler (outside of fraud detection) than what Uber has to do to get you from A to B.
