What would the world be like if there is only Linux and no Windows?

The debate never ends with Windows vs Linux. I just like to bring up a few thoughts here.

If there is never Windows in the first place, how far or fast will the world advance technologically?

We paid for using Windows and Linux is free but I think Windows deserve it’s due credit for getting the world up to speed in IT technology. Can Linux achieve this with the same timeline?

I am not pro Windows. But I learn some of my programming skills via Windows platform. I am now a Linux user but I am not going to criticize Windows because it has helped me along the way.

Windows and Linux will co-exist together. Let’s
lessen our criticism of Windows and focus on making Linux a better contestant.
