I'm not convinced.

Linux now has pretty broad adoption, but it is difficult to report. Look at most of the people in this forum -- in this demographic, people are at home with Linux on the desktop.

If there's a problem that can be solved by knocking up a quick script, people here will invariably turn to Linux.

In this demographic, desktop Linux appears to have pretty broad market share. And it appears to be increasing.

Then of course, servers -- only a vanishingly small % would seriously consider running Windows servers, and that number doesn't appear to be growing.

Android adoption seems to be > than iOS too. Android is Linux.

I see there being a bit of a "digital divide". Those who are computer literate, able to use general purpose computers to solve problems (and recognise and appreciate the freedom needed and given in order to be able to do so); and those who are not (and just need to look at ads on Facebook). Those who aren't, are also not likely to be early adopters of a cryptocurrency.

As people begin to recognize the importance of being on the right side of the divide, adoption is likely to grow. However, some people will never be able to cross over.

It's the same as the Web in the late 90's -- a small % of people who used it, with mass adoption following as people recognised the importance of being "web literate". Some people were left behind.

That said, barriers to adoption are constantly decreasing too. Many flavours of Linux have been easier to install and use than Windows for a long time now. And it will become easier and cheaper to adopt cryptocurrency in the future too.

EDIT: And I don't get the Ubuntu hate. It's not closed source at all..... Mark has done wonders for the Linux ecosystem.
