That's a bit revisionist. Network effects were obvious when Google acquired Youtube. Google Video had the edge technically, but it didn't matter because Youtube had the users/content and Google saw that very clearly in their user growth before they made their offer.
ChatGPT is losing their brand positioning to Google, Anthropic, and Chinese Open Source
Altman knows this and why he called code red. If OpenAI hasn't produce a fully new model in 1.5 years, how much longer can they hang on before people will turn to alternatives that are technically better? How long before they could feasibly put out a new model if they are having issues in pre-training?
I'm not sure about it having the edge, I thought Google video had a worse interface between them at the time. But that point feels eerily relevant anyway: a lot of normal people I see don't care if Claude/Gemini/etc are better models technically, they're comfortable with ChatGPT already.
A lot of YT's growth at the time was word of mouth and brand among the population, which is currently ChatGPT's position.
