It's that and more. The tech is a moat. The business model is another moat. Part of the problem is the business model allows for some shady practices like selling $1 services for $0.80 to kill competitors (like the taxi industry and other startups in the same space). Then raising prices to $1.30 over 20 years. I don't think it works though. It just ends up with everyone dead and us buying enshittified taxis at 2-3x the price later because nobody else has a ride sharing app.
