The recklessness kinda works for everybody until some point. Go fast and break things... then cash out before investors realize, unless you manage to capture the market so you can keep breaking things because people will swallow.

What's working for them is having a huge amount of resources and very good people to design a cutting edge agent harness, RLHF the hell out of their models, and build out a tremendous amount of inference capacity. I'm sure their process for making code changes in any of their client apps is very fast, but a TUI built around a chatbot is also not a particularly complicated application. So yes it's working for them, but the vibecoding that they are selling is clearly not what they are doing in practice.
