let me know if i should do these kind of theoritcal computer science breakdowns like P vs NP, or you want me to cover some other topic?

Yes p vs np would be a great topic for a video .

on Did AI Just Solve an 'Impossible' Problem? | Full Breakdown
The GPU never leaves Singapore, but its computing power can be used from anywhere. That's the part export rules struggle with. What should I break down next? Reply with a number: 1) P vs NP, explained visually (your most requested topic) 2) How Discord handles millions of messages in real time 3) How Google Maps finds the fastest route in milliseconds 📚 For my students: a fully rebuilt, modern version of my course is coming soon.
