I still wonder how we could improve IPC on a system, by other means than text protocols.
I was reading some cyberpunk books this summer, and they all came with a different approach when it comes to the "interface of the future".

The most "common" one is a 3D which you can interact with just like you'd do in real life: handwrite notes, read paper sheets, etc... It has to be the most intuitive way to do computing, as there is no new skill to mastef while in the system. I suppose that programming in this environment is like doing mechanics in real life, closer to craftmanship.

Another interresting idea was neural plugs, so you could "feel" data streams, and process them dirrctly inside your brain. This gives you full power over the system as it becomes an extension of your brain, at the cost of putting you in danger (no need to explain why you'd be afraid of hackers...)

And last but not least: AI. Some authors simply rely on a robot that would do all the search for you, computing from a huge database where every document is archived. You then talk to this AI to find what you are looking for.

All of these would change computing drastically, so I wonder if, and when they would appear. The first one being the more plausible, seeing the hype with VR today, and the progress made in such direction
