"What does life on earth look like if we cure aging? Well, we better well cure the problem of giving birth at the same time, doncha think?" If we live healthy and young for 200 years, for example, giving birth may occur at older age. Why would you want to have kids every single year if you live to 200? Why not wait till you 118, for example.
Look at what happens in countries of Europe, for example. People choose not to have children enough to replenish the population, a so-called negative birth rate. This might happen in the future everywhere.

Back in 80s only really rich could get cell phones. They started the trend. Now you and I can enjoy it too. Yes, it took some time, but they are cheap and everybody can afford them. The rich lead the way.
Same with curing aging. It must be billionaires leading the way. You and I can not afford spending millions on biomedical research. Or can you?
I say few dozen years from now, our kids will wonder why we all did not invest in our future and make our 80s and 90s to be healthy living time instead we died slowly in decrepitude and pain.
Or think this way, ask your grandma if she loves to have Alzheimer or Parkinson.

1) The number of grains is about 10^123. Number 123 sounds familiar. 2) Changing the size (radius) of the universe from 15 billion years to say 30 billion years does not change the size of the volume grain that much, which is about the size of an electron! Wikipedia says: "The classical electron radius is 2.8179 × 1015 m" 3) You can try to back calculate the size (radius) of the universe, given that the size of the volume grain is equal to the size of the electron.. It turns to be 27.2 billion years (which might be about twice as much as the size of the currently visible universe.)
Here are the back of the envelope calculations:
Radius of the universe, assume, = 15 billion light years = 4.73*10^17 light seconds Speed of light = 3.00 * 10^8 m/s Universe radius, r = 3.00*10^8 m/s * 4.73*10^17 s = 1.42*10^42 m Area of the sphere of the universe, A = 4*pi*r^2 = 2.53*10^53 m^2 Volume of the sphere of the universe, V = 4/3*pi*r^3 = 1.20*10^79 m^3
Planck distance = 1.616*10^-35 m Number of pixels (grains of the size of Plank distance) on a square meter = 3.83*10^69 Number of pixels (grains) on the sphere, Ns = 9.69*10^122
size of volume pixels (grains) in the volume of the sphere, rV = 1/ [ ( Ns / V ) ^ (1/3) ] = 2.13*10^-15m
(check: number of volume grains in the universe = number of grains in 1m^3 * volume of universe in meters = (1/2.13*10^-15)^3 * 1.20*10^73 m^3 = 9.69*10^122) nanotech.republika.pl
How can you tell that precisely an average human hair width? 45nm*1133=50895 nm, or 50.895 micrometers? Damn, the 5 nm of that 50895 is a single molecule size!
Or you just sampled one from your scalp and measured it?

Interestingly,
1) The number of grains is about 10^123. Number 123 sounds familiar.

To achieve a full orbit, the velocity must be 7.8 km/s or about 23 Mach. 5200m/s is not enough to stay in orbit. It more like suborbital flight.
