This reminds me of that Ben Shapiro quote that goes something like "If sea levels rise, do you think people won't just sell their house and move?"

How can people these people move? Especially if they own these places.

This is entirely a collection of terrible takes and misrepresentations.

I would be worried about this if the plan was for it to only support MacOS on mainline Firefox. This is Nightly, two release cycles ahead of regular Firefox, and support will be coming to other platforms: "porting it to other POSIX systems (Linux, Android) will be easier than Windows, due to the overlap with macOS" (https://developer.mozilla.org/en-US/docs/Mozilla/Projects/We...)

There's multiple apps that let people hail cabs: Gett, Taxiapp, etc.

Gett looks like it offers its own services though (i.e. its own cars?)

I'm talking about hailing a regular London Taxi, not any car.

Gett gets you an actual taxi (regulated fare and all) in most of the UK, not certain about London.

Markets haven't been doing a good job of it so far, why would they in the future?

Yeah we live in the time where companies look quarter to quarter....or are rewarded by the market by growing like Uber where profits don't even matter.

Not sure we can hope for them to look into the future very far / care.

The likes of Uber are valued highly precisely because investors are looking very far into the future where these companies might become highly profitable.

I'm not convinced that is the case.

I really think there is a difference in "look at this market share" and critical thinking about how Uber can get to sustainability.

I think the whole tech company IPO is a weird otherverse that isn't as much about the future as folks think.

Markets work based on information. Lack of information causes consumers to buy something they don't want to buy, e.g. negative effects on the environment. Markets should be controlled in a such way that the seller must tell what they are selling, including environmental effects, and they must not lie.
