Yes, most projects are pure hype. The amount of AI peddling on Twitter and YouTube is unprecedented. I wish the community were a lot more humble in that regard. That being said, there are a lot of legit use cases and customers in need of solutions that cannot be done quickly via a few API calls to OpenAI and require a lot of customisations and hand-holding. AI is hyped a lot, but there are companies out there, and I like to consider us being one of them (bias, I know), that think about how to enable customers to solve/improve real problems with the help of AI instead of making a quick buck by peddling the latest doc-chat solutions.
From that perspective, AI is not the new crypto. If you ignore the noise and focus on the actual work, you will find a lot of good things about this field, and I might say even breakthrough advances, that help us reconsider what intelligent life really means.
Disclaimer: we are one of the first "chat to your docs" companies that came out as soon as ChatGPT was released when all we had at our disposal was text-davinci-003 and basic vector stores. Now, we do mostly other things.
