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.

Not for science history. It's very hard to grasp what the hell the LHC is about. First tell me why how they figured out water wasn't an element but a combination of two.

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.
