It's not so much the fork but the memory cost. Each of those subprocesses has at least one call stack = 2 megabytes of memory. 2 megabytes per connection is many many orders of magnitude more that you would use in an asynchronous server.

Consider the proportion of the cost of an Uber ride that goes to the driver compared with the proportion of the cost of an airplane ticket that goes to the pilot. A driverless car has the potential to be much cheaper, but a pilotless plane would not be much different. Many new train systems are automated. The cost of retrofitting older systems is just too great.

people are mostly interested in what is successful and backprop/gradient descent (with certain specific architectures) is what has been dropping error rates on all sorts of tasks in recent years.

I think there's something to say about it being safer to bike in general in Netherlands vs in the US. Often in the US you are riding next to busy traffic, while in NE the bikes are better protected. Along with other things too: like a car driving population that is careful about bicyclists.

So, it's not exactly like saying I don't wear a seatbelt because I drive the speed limit. Rather it's like saying I don't wear a seat belt because I live in a different country where accidents are less probable.

Can someone explain what the "spread operator" is and how to use it?

We can live perfectly healthy lives without meat. That said, I have no problem killing an animal that lived a full non-tortured life for food. I do think we owe more than buying the expensive whole foods meat. I think we should all go through the experience of killing a cow, pig, lamb, and chicken. Killing animals shouldn't be completely abstracted away from society - we need to understand what we are doing in a hands on way.

Times Square generates 11% of NYC's economic output? 385k jobs? I find these numbers difficult to believe.

Dude, it's totally fucked. Like removing the sea from seaside towns. i'm sure if you're a mediterranean fisherman you would not be happy having the sea forcibly moved away from your home... The environmental impact is probably immeasurable.
