My understanding is that they are "hunting for variety" in seeds before they disappear. There may be additional advantages for having older seeds too. This is pretty standard practice, and the raison d'etre of seed banks. But I'm not an expert at all. Just general knowledge stuff for me

Specific adaptations were cultivated for specific changes. But really in nature, what keeps things alive (evolutionary speaking) is variety. Example: if you have corn seed engineered for highest yields at ClimateX (let's say temperate) and SoilconditionsY, etc. and those change, then the yields may be drastically lower, or the seed may not yield at all. So you need variety to ensure survival.

This is what all tech money has been doing - converting from "fake money" (esp. highly overvalued stocks, etc) to real money. Same same with crypto. They are all following the McDonald's strategy. They can offset the leveraged-purchases on their balance sheet for tax reductions, and then end up owning all assets. This is kind of how we got where we are.

Well, when the US government stops using consultants from Bain and McKinsey to help them with research, you will find out. I wouldn't hold my breath though.

Oh it does more than that. How about AI that pattern detect retail trading and makes bets against predictable behavior?

Seems to me like you know what the answer is - regulation.
