Also, his analogy of Linux running in front of Indiana Jones' boulder is incorrect as there is no boulder coming up behind Linux. His only argument for that is just the age of Linux.
Speaking of which, he separates Windows into different iterations--3.x, 9x, NT, etc), but keeps Linux as a single OS. The Linux of today is nothing like the Linux of the 90's. You can argue that they are separate operating systems.
I think he, as a person, tends to see everything as a glass-half-empty situation. All through history, traditional methods have given way to newer methods. Linux is evolving just like everything else. It is still Linux.
But the divisiveness and cancel culture, led by universities, is a problem. Of course, while I have Linux Mint on one PC that is almost only used (not by me) for Internet streaming, I myself do not run Linux, for while I have tried every major and some minor distros and think it has much potential as a Desktop (which is all I run, with about 7 browsers and hundreds of tabs, etc.), I do not want to use the time I would need to do the migration find all the programs and do all the customization that I have done on Windows to make it work as I want it too. And there is also the quasi-legal multimedia codec issue, though for which there is Fluendo.
Yet I am certainly glad there is an alternative, and look at distrowatch occasionally and read reviews on certain ones (I find Dedoimedo to provide the best, like https://www.dedoimedo.com/computers/best-distro-2016-2020.html) and might install one on a new SSD i ordered for backup.
Thank you for the help and info you have provided. Grace and peace thru Jesus the Lord.
