Not as great as it seems. The thing is, everyone’s retirement is tied to real-estate. The numbers my vary country by country, but nearly all pension funds and mutual funds have significant exposure to real-estate that is just ignoring the issue that those properties may become uninsurable. That’s before what happens due to the economic disruption of all those cities slowly, then at an increased velocity, relocating.
It’s not going to be pretty.
I know youtube has been selective about rollouts, but I use uBlock, sponsor block, and ABP in chrome and have had zero issues.
