I think your surmise is probably wrong. It's not that their growing to fast, it's that their service is cheaper than the actual cost of doing business.
Growth isn't a problem unless you dont actually pay for the cost of every user you subscribe. Uber, but for poorly profitable business models.
> Since its founding in 2009, Uber has incurred a cumulative net loss of approximately $10.9 billion.
Now, Uber has become profitable, and will probably become a bit more profitable over time.
But except for speculators and probably a handful of early shareholders, Uber will have lost everyone else money for 20 years since its founding.
For comparison, Lyft, Didi, Grab, Bolt are in the same boat, most of them are barely turning profitable after 10+ years. Turns out taxis are a hard business, even when you ramp up the scale to 11. Though they might become profitable over the long term and we'll all get even worse and more abusive service, and probably more expensive than regular taxis would have been, 15-20 years from now.
I mean, we got some better mobile apps from taxi services, so there's that.
Oh, also a massive erosion of labor rights around the world.
I suppose my comparison is that Uber eventually turned a profit and mostly displaced the competitors.
I don't see the current investments turning a profit. Maybe the datacenters will, but most of AI is going to be washed out when somewhere, someone wants to take out their investment and the new Bernie Madoff can't find another sucker.
