I'm not at all saying that tech is somehow "dead". What I am saying is that many of the non-engineering roles that were popular in tech over the past 15-20 years are either going away or will continue with vastly reduced numbers of people. If you're someone who did agile training for the past 15 years and are now in your 40s and were laid off, I sincerely doubt you'll be able to get a job as an agile coach before the end of your career that pays as much as in the 2015-2020ish timespan.
