Anthropic ARR went $1B -> $4B in the first half of this year. They're getting my $200 a month and it's easily the best money I spend. There's definitely something there.
It makes me perhaps a little sad to say that "I'm showing my age" by bringing up the .com boom/bust, but this feels exactly the same. The late 90s/early 00s were the dawn of the consumer Internet, and all of that tech vastly changed global society and brought you companies like Google and Amazon. It also brought you Pets.com, Webvan, and the bajillion other companies chronicled in "Fucked Company".
You mention Anthropic, which I think is in a good a position as any to be one of the winners. I'm much less convinced about tons of the others. Look at Cursor - they were a first moving leader, but I know tons of people (myself included) who have cancelled their subscription because there are now better options.
The shell of the IDE is open source. It’s true there is some risk on the supply of models and compute but again none of those, except MSFT which does not even own any of the SOTA models, have any direct competition. OpenAI has codex but it’s half baked and being bundled in ChatGPT. It is in nobodies interest to cut off Cursor as at this point they are a fairly sustained and large customer. The risk exists but feels pretty far fetched until someone is actively competing or Cursor gets bought out by a OpenAI.
Again, what proof do you have that there is zero complexity or most being driven by the sandwich filling. Most of OpenAIs valuation is being driven by the wrapper ChatGPT not API usage. I have written a number of integrations with LLM APIs and while some of it just works, there is a lot of nuance to doing it effectively and efficiently at scale. If it was so simple why would we not see many other active competitors in this space with massive MAUs?
