David Sachs outlined how he thinks about the bigger picture of the AI tech stack on the most recent All-In Podcast (48:43). I think it's a very useful mental model so I have reproduced it here so I have something to link to from other articles I write.

1. Chips, silicone, Nvidia
2. Foundation models, open AI, open source models etc
3. Infrastructure, developer tools, vector databases
4. Applications

Talking about layers is pretty popular at the minute.

David Pierce repeats the complaints from makers about Apple in a recent Vergecast episode.

It’s is actually worse than it was before. You’ve made our lives harder in the name of pretending to make our lives easier

He also summarizes the situation quite succinctly:

Apple is now embroiled in several very high profile litigations. It's going to be interesting to see how it unfolds, the results affect us all.
