I think it's very clear that most of the truck drivers will be replaced by autonomous trucks driven by software. Human drivers need to sleep, robots don't. As our storage warehouses are already mostly on the wheels and logistics is optimized that the required goods arrive just in time, all this makes sense. The change might even be very fast. 30% of truck cargo might be driven by robots in the end of the decade.

I'd always have liked that I could transfer a file or an stdout/stdin stream directly in the middle of an open ssh session. Also the file transfer / stream should be carried over nested ssh connections.
Imagine that you could just pipe the output from a command into some magical ssh command in a remote machine and your ssh client would ask where you would like to pipe the stream in your local machine.

I knew I shouldn't have asked Wolfram Alpha The Answer to the Ultimate Question of Life, the Universe and Everything.

Now imagine a Beowulf cluster of those...
