Code Search seems a limited market so I would be surprised if their plan wasn't to go after deeper code tooling in the future. Otherwise I don't see how their $2.6 billion valuation made sense. They likely thought that an iterative approach based on human encoded code understanding would allow them to build better systems. Pretty reasonable assumption 1+ years ago. Then GPT3/4 proved that you could just dump data into an AI and probably get an even better result.
