Uber is worth less than zero. They already are at full capacity (how many cities are there left to expand) and still not profitable.

It may not be profitable but it's utility is worth way more than zero.

I don't like Uber but no one is taking them over for a long while. They are not profitable but they continue to raise prices and you'll see it soon. They are doing exactly what everyone predicted by getting everyone using the app and then raising prices that are more expensive than the taxis they replaced.

Decoupling from OpenAI API is pretty easy. If Google came up with Gemini tomorrow and it was a much better model, people would find ways to change their pipeline pretty quickly.

Uber has multiple moats: The mutually supporting networks of drivers and riders, as well as the regulatory overhead of establishing operations throughout their many markets.

OpenAI is an API you put text into and get text out of. As soon as someone makes a better model, customers can easily swap out OpenAI. In fact they are probably already doing so, trying out different models or optimizing for cost.

The backing isn’t a moat. They can outspend rivals and maintain a lead for now, but their model is likely being extensively reverse engineered, I highly doubt they are years ahead of rivals.

Backers want to cash out eventually, there’s not going to be any point where OpenAI is going to crowd out other market participants.
