...in parts of the internet (e.g. email) we do need to replace the current "receiver pays" model with a "sender pays" model or even a "both pay" model. That will instantly eliminate spam, close mail relays and shift the source of viruses to more controlled areas.

The SunOS 1 machine I used in 1986 had SunView. It could drive multiple screens via separate frame buffers and I could switch between them by moving the mouse to the screen edge.

There's surely not much of a technological leap to stack those frame buffers behind the one screen and switch via keystrokes.

This would be because those Europeans have put their money up front to build the road you're now driving on. Now you're paying them back with interest, but you also save money (in theory) by spending less time commuting and more time earning a living.

I thought Americans understood capitalism.
