(Author of the newsletter here) It's early days, but the simplest use case has been to improve employee productivity (Github Copilot, ChatGPT etc.). The Stripe CEO just tweeted that over half of their employees are using an internal LLM tool they built (folks who build internal tooling know how hard it is to drive adoption to a non-mandatory tool): https://twitter.com/patrickc/status/1681699442817368064?s=20

There are other companies which are doing some crazy experimental things which may have a large impact. For instance, Truveta is cleaning up on millions of medical records, training a model on that data and using that to drive research about patient care. Too early to tell if LLMs will actually transform companies beyond slight bumps in productivity, but to me, it feels like the cloud computing moment from 12-15yrs ago.
