Think about how mobile our computing devices have become and the convergence of different devices?

such as cameras, phones, computers, etc. What do you think the computer of the future will be like? What capabilities will it have that computers currently donât have? Do you see desktop computers becoming obsolete in
I mean becoming obsolete in the near future?

Answer
Well, D-Wave's quantum computer is worth watching.

Personally, I don't see desktop computers becoming obsolete especially soon.

I mean, I'm typing this on a mechanical keyboard and I'm looking at a display on my desk. That's the same as I used in about 1972, except back then it was a Tektronics storage display connected to a CDC mainframe. It's a setup I'm comfortable with. I've used smartphones, and I've used projection walls but for editing documents this is better. Of course, that's just the human interface - whether the computer is a mainframe, cloud, under the desk or built into the keyboard is of less concern.

I can see voice recognition finally making the leap to actually working for everyone, regardless of background noise and your accent.

For hardware, if 3D printers take off, I can see 3D laser or ultrasound scanners becoming more common, and some medical diagnostics becoming more mainstream (again, perhaps ultrasound or MRI based)
