So you insist on negating the benefits of not only engineering, but also science? :) The question of what benefits space program brought to humanity is old and well known, I'll only remind of one of it. The modern generation of space e

Scott Aaronson, from shtetl-optimized fame, describes his work as on the boundary of math, physics and computers. P vs. NP problem is a CS problem yet has some apparent consequences in quantum world. Not quite coding though.

Starship has another advantage over Shuttle orbiters - orbiters were about 80 tons when landing, while Starship is about 120 tons empty, but has much bigger size - diameter and length, which makes it braking higher in the atmosphere where t

Not quite correct. It's useful to have some remote parts of humanity which could be relatively safe when other parts are busy making threats to each other. Earth still has some remote places - ask any doomsday prepper - but Moon and Ma

Good video, many good points. "Focus on the mission" What's the mission? We're "returning to the Moon" - what does it mean? Boots on the regolith? I somehow doubt that. USA did that half a century ago, we'
