(ie., costing around $1B at current costs)
I’d be inclined to update that downwards, maybe an order of magnitude or so (for a total cost of ~$10-100B). Given hardware improvements in the next 5-10 years, I would expect that to fall further to ~$1-10B.
Am I reading it wrong or is there a typo?
>perhaps a social stigma can develop
Social stigmas get traction via contempt, so that sounds promising.
