So... I don't think this is certain. A surprising number of people pay for the ChatGPT app and/or competitors. It's be a >$10bn business already. Could maybe be a >$100bn business long term.
Meanwhile... making money from online ads isn't trivial. When the advertising model works well (eg search/adwords), it is a money faucet. But... it can be very hard to get that money faucet going. No guarantees that Google discover a meaningful business model here... and the innovators' dilema is strong.
Also, Google don't have a great history of getting new businesses up and running regardless of tech chops and timing. Google were pioneers to cloud computing... but amazon and MSFT built better businesses.
At this point, everyone is assuming AI will resolve to a "winner-take-most" game that is all about network effect, scale, barriers to entry and such. Maybe it isn't. Or... maybe LLMs themselves are commodities like ISPs.
The actual business models, at this point, aren't even known.
But not profitable yet.
The original idea of ride-sharing made sense but just like airbnb it became an industry and got enshittified.
This also means that they sometimes fleece tourists but when they figure you know the city well they don't dare :) Often if they take one wrong turn I make a scene about frowning and looking out of the window and then they quickly get back on track. Of course that's another usecase where uber would be better, if you don't know the city you're in.
yeah thanks no, I'm paying for an Uber. For all the complaints over Ubers business practices, it's hard not to forget how bad taxis were. Regulatory capture is a clear failure mode of capitalism and the free market and that is no more shown than by the taxis cab industry.
One time I told one of my Dutch friends I often take a cab to work here in Spain when I'm running late. He thought i was being pompous and showy. But here it's super normal.
Uber (Or cabify which is a local clone and much more popular) here on the other hand is terrible if you don't book it in advance. When I'm standing here on the street it takes 7-10 minutes for them to arrive while I see several taxis passing every minute. So there is just no point. Probably a factor of being unpopular too so the density is low.
I also prefer my money to end up with local people instead of a huge American corporation.
