Might take longer than 50 years, but I would bet things go even further to simply "salmon" -- the not-lab-grown variety, that is, and same for other meat.
Nah, all they will eat is salmon, it will be excess from the iron fertilization they use to counteract global warming. They will have to harvest the salmon boom to protect the algae bloom or the albedo will drop and cook everyone.
It's funny that these are marketed as luxury products that sell for under $40. I mean, I know inflation is a thing, but $40 was not a lot of money back then.
As a side note: the 70s saw a particularly high level of inflation. Note that the equivalent price in 1980 was ~$85, so it doubled in one decade. If that level of inflation stayed constant (doubling every decade), then it would be equivalent to about $1,280 today.
many products promoted as "luxury" are about telling middle class people that their products imitate upper class signals, without that actually being true. Thus they're usually expensive for a salaried worker but not beyond affordable - whereas products that the upper class genuinely use to signal are well beyond the balance of wage labourers.
Wow. That and https://1.bp.blogspot.com/-w3Xc47mDO8E/YZvrzIxkirI/AAAAAAAAg... ("solid Honduras mahogany") really hit me.
I wonder what they see 50 years from now and shake their heads about what we squandered. My guess is "wild caught salmon" and atoll beach resorts.
