What would the shape of computing be 12-15 years from now? Here is where I think we will be:
My wrist watch will have my computer. When I reach office, I will place myself in front of a ‘dumb’ terminal – a monitor, a keyboard and a mouse. Embedded into the keyboard will be a smart card which will talk to my wrist watch (without cables). I will use a remote log-on software to connect to the computer inside the wrist watch – all applications will already be installed on the wrist watch and I will use them. It will also be possible to use the wrist watch as a pen drive of today. So all the data on the hard disk of this computer will be available in two ways: the remote log-on (which will also enable the use of installed applications), and USB (that is, minus the capability to use apps).
At home (and everywhere else), I will have a similar dumb terminal.
Microsoft will be dead – opensource (and portable) software like OpenOffice, and AbiWord will have caught up in terms of functionality. For profit firms of 2020 will provide support (and contribute to the enhancement to) GPL software.
Google will be going, but its offering of (office and other) applications as an online subscription (which will have become paid by then) will not be doing very well. People want to collaborate, but not at the expense of being tied down.
Electronics commerce will still have identity fraud Sorry guys. However, the total volume digitally traded will be rising steadily.
Digital signatures would be much more easier to use, and transparent to the unitiated user. However, it will not be free from its own share of frauds.
Operating systems will be very different from today: there will be no device drivers. Every device will be plug & play, and will use universal drivers. Linux will be the defacto standard.
You have some more ideas? Please feel free to share.
