I think this is too little, too late. Anyone who saw an advantage to using generic programming is already using something else. They've already invested resources in something besides Go; why spend the effort to switch back for what will, at best, probably be very mediocre support for parametricity compared to whatever they're already using?

Sure, so we'd better get started.

Humanity is at an incredibly high extinction risk. We have all sorts of incredible new technologies that could, at the very least, knock us back to pre-industrial society. They might just kill us outright.

We've already used all the easily accessible high-energy fuels, so if our current industrial society falls apart, we will probably never build another one.

If we don't get to space now, we will probably never get to space. Then it's only a matter of time until we get hit by an asteroid.

Or we'll just get killed by an engineered supervirus and skip the whole pre-industrial decay phase.

Going into space is our insurance policy.

Environmentalists will never be satisfied. There is always something to improve.

If humanity dies or goes pre-industrial because someone engineered a supervirus and we refused to put effort into space travel, all our conservation efforts won't really matter much.

Environmentalism isn't an excuse to give up on every other aspiration humanity might hold.

You can still use blood from a private company for the treatments you would use "public" blood for.

Feces are brown because they're full of expired blood cells (according to high school physiology class). So I think we're renewing it all the time.

Back in college I donated sperm for money. It's not like I was forced into it; it was just nice to have an extra source of income besides my student job.

This also enables sperm banks to retain recurrent donors, which means they can afford to do very rigorous testing amortized over several dozen sperm samples. DNA screening, urine tests, blood tests, etc. That wouldn't be viable under the blood donation model. I've donated blood 5 or 6 times but I doubt even that's enough to make it worth the kind of testing they did on me as a sperm donor.

Sperm banks manage to get very high quality, sanitary sperm despite many people doing it for the cash. The trick is to have recurrent donors you can test regularly, and to quarantine samples until they can be cleared in bulk.
