One of my proudest professional moments was when me and three others managed to reduce memory load of the game Wavetale from 20+GiB to under 3GiB so we could port it to Nintendo Switch.
The 100 TiB number almost gives me vertigo. Though in this context it was "just" 50%
I'd love to hear what was taking up that 17GiB if you can share, even if it is commonly optimized things like packing, still fun to hear about
