Is reality invented or discovered? Is math invented or discovered? Was automata theory invented or discovered? OK well then is the quicksort algorithm invented or discovered? Is LISP invented or discovered? Is my code invented or discovered?

Are invented and discovered just a matter of perspective?

I fear the graphene will fall by the wayside due to legal and social pressure. News sources have already pointed out that it is significantly more dangerous, if inhaled, than asbestos; another material this is insanely useful for a number of applications but is effectively blackballed as a engineer-able material. Another example is nuclear energy. Clean, abundant, and extremely safe. The fear of radiation exposer has…

Also unlike asbestos we may be able to manufacture products which use an astonishingly small mass of graphene to be useful. Perhaps that small mass can be suspended/isolated with other materials that will mitigate the likelihood of impacting humans.

For some reason I believe that cosmetic gene modifications will be more readily accepted than GMOs.

Plus, it will end racism and make anime hair color a reality.

Look, 10% of the people in my office building already have neon-colored hair. They use dye.

I'm not sure I agree with ending racism. Maybe you were being tongue-in-cheek. I mean, presumably someday far in the future, everyone will have access to the ability to alter fully their entire genome. I would think in the next XX years, though, there will be plenty of remaining distinguishing features beyond skin color, and more importantly, plenty of people without the money to make any changes. Besides that, I'm h…

>Maybe you were being tongue-in-cheek. Just a bit. >plenty of people without the money to make any changes. >I speculate class will lead the charge next. Exactly, it transforms the race problem into a class problem. People will probably discriminate based on how many designer genes you have. With time, most governments (not necessarily the US) will realize how much they can save by giving people healthy genes from th…

>With time, most governments (not necessarily the US) will realize how much they can save by giving people healthy genes from the start, and it won't be as much of a class divide.

The poverty-as-disease model already shows that governments could save money by treating/preventing poverty rather than providing lifetimes of palliative care[1]. The problem is the moralizing about poverty.

This means curing: Color Blindness, Liver Disease, Hopefully Cancers, Genetic Defects, MAYBE one day Aging?

More likely the first (profitable) applications will be: changing eye color, hair color, losing fat, changing height, changing skin tone. Billions in each market.

I highly doubt cosmetic uses will be the first.

The FDA approves drugs based on risk vs. safety. Having the wrong eye color is pretty low risk in terms of health.

Gene editing will be used in fatal or severely disabling diseases with no other options. Even if there are severe side effects, the FDA will likely approve them.

Blockchains. Distributed consensus is incredibly powerful. It will allow us to rebuild our society around individuals instead of corporations and governments that formed because economic transaction costs were so high that economies of scale (and sometimes the use of force) were required to coordinate our society.

All economic activity will be blockchain-mediated. It will make us wealthier and freer.

The problem with GMO is that it's basically a vendor lock-in scheme for agribusiness giants. It's not a good engineering solution to the real food problems we face. Of course, the DONT EAT THE SCIENCE OR IT WILL GIVE YOU THE CANCER political nonsense is wrong. That doesn't let GMO off the hook, though. The problem it attempts to solve, on the surface, is increasing the productivity of monocropping. But productivity i…

"The problem with GMO is that it's basically a vendor lock-in scheme for agribusiness giants." Hybrid seeds already did that 50 years ago.

Are hybrid seeds designed to be one use only like terminator seeds? How is the vendor lock-in structured?

Yes, many hybrid seeds are one use only. Farmers cannot save and resow the seed. They need to buy the seed each year.

The seeds might not be sterile, but even then the seed would produce unreliable plants.
