Which part of Figma can you build with 20 engineers? I think we're still not close to a small team building real-time collaboration software at scale that actually works at the quality level that customers expect.
I think we can expect a bifurcation: managerial jobs that will require a lot of breadth and engineering jobs that will require a lot of depth. The manager engineers will have AIs doing all sorts of things for them across the stack. The deep engineers will develop an expertise that the AI can't get to (at least not yet).

Nvidia has been working on CUDA for 16 years and for the past few years building ML use cases on CUDA. AMD is late in the game with ROCm. That said, I think the future is bright for AMD. The MI300X looks great and they're spending a lot on making ROCm better and fully PyTorch compatible, which will automatically make all of the PyTorch-based software AMD ready.
Their software is definitely improving and will get a whole lot better in the next few years. It's worth many billions for companies to exit the Nvidia lock-in.
