I enjoyed this article. I was a working programmer from the mid ’90s to the mid 00s when just knowing one comprehensive development tool/language and perhaps a few side 3rd party APIs were enough to be employable (my expertise was in pre-.NET VC++ and .NET C# Winforms.) The situation since the mid 00s has been completely ridiculous. It seems that getting a job on the front end is a tournament to see who can bust his a33 to master the latest k3wl thing. I understand that the database side is much more stable, and indeed it appears that the career of data scientist is a very good field that a young version of myself would be keen to pursue.
