Ask
What does he say about protecting creative attention?
Attention is treated as an environment you design—not a resource you force.

What should I change first?
Protect the first hour: remove inputs, define one constraint, and return to the work before reacting.

Scaling AI: The Memory Wall
Ask
What is limiting AI infrastructure from scaling faster?
Memory bandwidth, interconnects, power delivery, cooling, and advanced packaging are becoming the real constraints.
12:1828:44
Why is memory becoming the first wall?
Compute is scaling faster than data movement. More bandwidth and tighter packaging are needed to keep accelerators fed.

Electron Transport Chain: Powering ATP Synthesis
Ask
How does the electron transport chain create ATP?
Electrons move through membrane complexes that pump protons, building a gradient ATP synthase converts into ATP.
