I would say you can get to this point far below 100 million people, especially on web. Some people are truly special and have some kind of setup you just can't easily reproduce. But I agree, you do really have to be confident in your ability to control rollout / blast radius, monitor and revert if needed.
The use of "storage.googleapis.com" is probably because it's an "authority" domain that apps can't easily ban without side effects. Buckets can typically be used as a static site host where u can host a client side redirect, depending on how you set it up you can make it almost impossible for an app to ban a campaign in real time.
Is this constitution derived from comparing the difference between behavior before and after training, or is it the source document used during training? Have they ever shared what answers look like before and after?
Unfortunately, I feel like I'm in the minority here, but AI has been really helpful to me and my doctor visits when it comes to preparing for a ~10-minute appointment that historically always felt like it was never long enough. I can sit down with an LLM for as long as I need and discuss my concerns and any potential suggestions, have it summarize them in a structure that's useful for my doctor, and send an email ahead of the appointment. For small things, she doesn't even need me to come in anymore and a simple phone call to confirm is enough. With the amount of pressure the healthcare system is under, I think this approach can free up a lot of valuable time for her to spend with the patients who need it most.
IMO eliminating as much client side authority as possible is a very good foundation for MMOs where the latency is acceptable or factored into all aspects of the game (looking at old school runescape as an example). Very cool project!
Not dismissing your first argument but we had good success hiring talent through Discord servers. If you want to reach the same audience that attends hackathons and such it's in my experience the best platform.
