+The Unix operating system project appears to have started in 1969 at Bell Labs.
+Something resembling contemporary Unix-like systems may have been developed in
+1973 when Dennis Ritchie and Ken Thompson rewrote the Unix kernel in C. Both of
+these important milestones, unfortunately, predate me by a number of years.
+
+Nevertheless, operating systems created in the image of Unix and, more
+importantly, that inherit its philosophy, have survived. Linux and OpenBSD are
+two such systems that I am personally familiar with.
+
+Operating systems like OpenBSD and Linux are free and open-source alternatives
+to commercial operating systems such as Apple macOS and Microsoft Windows.
+OpenBSD is developed by a group of hackers led by Theo de Raadt. Linux is
+community-driven, although, increasingly and ironically, under the stewardship
+of corporations such as IBM and Microsoft.
+
+Commercial operating systems, and the corporations behind them, are becoming
+increasily hostile towards their users. Viewing their users merely as a means
+to an end, the unbridled harvesting of personal data for targetted advertising,
+influencing the behavior of the masses, and training generative neural networks
+has become their primary objective. the book 'The Age of Surveillance
+Capitalism' by Professor Shoshana Zuboff documents in detail unassailable
+evidence and poignant consequences of the surveillance activities by these
+corporations.

 The year 2020 transformed my personal computing experience. In March 2020, I
 stumbled upon Arch Linux and discovered that I could customize my desktop
 environment to look and work any way I liked. I exercised that newfound freedom
