Also your timeline presumes self replicating spaceships exist or could exist. Have you ever thought about what kind of spaceship could mine metals, smelt them, make glass, build a chip fab etc?
The sort of technological capabilities we have today would sound laughable to people a mere thousand years ago. Who knows what will be doable in a few million years, which is a blink in the grand scheme of the cosmos.
Years later my boss was telling me how satisfied he was that he could throw any problem in my general direction and it would be gone in no time. There is nothing like the risk of losing his work permit to motivate a young guy to work himself down to a crisp, all for peanuts.
My partner often comments when I’ve been a little grumpier than usual by saying, “you should go on a bike ride.”
It really works wonders on the soul (and the more physical heart and lungs) getting out for a spin in the fresh air.
More generally, there is a lot more to each stage and to the race as a whole than the general classification.
If power to weight is all we cared about, we could rank all riders based on their power curve as measured on an indoor trainer and call it a day.
This makes a lot of sense to me. A very singular goal of "maximum output" without much need for fine motor skills and strategizing. I'd guess sprinting/marathons might have similar issues?
Nowadays I am convinced that what happened was completely explainable by the Lipid Energy Model [0]. Five days a week I was doing 60~90 minutes of cardio in the morning after skipping breakfast. Exercising in a fasted state while on a low carb diet meant that I had very low glycogen in my muscles and liver, which meant that the muscles had to mobilize fat as an alternative source of energy. Since fat is not water soluble, transporting fat through the blood stream requires packaging it inside a micelle wrapped in phospholipids -- a lipoprotein. Hence the elevated LDL & apoB.
The solution is simple: consume some carbs before and/or during exercise, and learn about the translocation of GLUT4 receptors if you are concerned about hyperinsulinemia.
So go ahead, write your own date library, your own Unicode font rendering, compiler, OS, game engine or what ever else people tell you to never do because its hard.
Painting in broad strokes, of course. I'm sure somebody somewhere is working harder than ever, but it is not the norm. Long walks in the park and meeting with friends doesn't contribute to the tax base.
