No, you can't have any guarantees. As they said in my High School Natural History class, 'The only thing constant is change.' But even without a contract written in granite, don't you think we should be looking into the many things we're discovering we can do with carbon? Hydrocarbons, and (CHON) Organic Chemistry in general?

Yes, his statement was also overly broad. 'No Barrier', indeed.

There are MANY important things to do, and MANY people that we have to keep busy if we are to get there. (Since we clearly can't stay here..)

I seem to remember Indium going for something like $100 an ounce and this was several years ago.

It might be now, where gold was a decade ago.

If it could be displaced by carbon, it would be. There must be applications that really call for it.

One I've heard of it, that it's used in low-temperature soldering, like of mil-spec stuff.

I've long said that high-tech stuff would soon devalue to where it's only worth its scrap value, but that it where high-tech equipment stands now. It's not repairable, it's quickly outdated, and its only value is in the gold, palladium, and stuff like indium that may be on the circuit boards and in the chips.
