> Silicon Valley can do ad networks extraordinarily easily.

This is just not true, building an effective advertising platform costs significant amounts of money, time and people.

Remember that you need to hire a sales force for this, and sales scales linearly rather than sub-linearly like engineering.

Additionally, you need to spend a lot of money dealing with fraud, fake and malicious ads.

Furthermore, you need to figure out where to put the ads and how to rank them.

Finally, advertising is a zero sum game (given that the internet has already killed lots of print & OOH advertising), so the only way to win is to better better/cheaper (preferably both) than Google/Meta/Amazon. Best of luck with that (although to be fair to OpenAI they did hire Fidji who knows a lot of this stuff from her time at Facebook).

They don't have a Sheryl Sandberg type figure, and she was also really important in selling FB ads to large advertisers.

Just looking at their leadership team I don't see anyone with a background in (successful) ads companies, so I'm pretty sceptical that they can build this out quickly enough to matter.
