It is and it isn't. I remember the first time I thought "this software is just X that everybody forgot about, reinvented again". That was 2005. Not coincidental

It is and it isn't. I remember the first time I thought "this software is just X that everybody forgot about, reinvented again". That was 2005. Not coincidentally that was a decade after I started working as a sysadmin. Venkatesh Rao says that there comes a point in your life when you realize things you thought were permanent are temporary, and things you thought were temporary are permanent; he uses "40" as a good rubric for that developmental stage. IT goes through many pendula, whether it be containerization vs. amalgamation, or thin clients vs. thick. What, over time, you learn to hold on to is the tools that have lasted decades and will probably continue to. Right now the pendulum is starting to swing back towards amalgamation, and it will probably swing back towards containerization again in another decade. Whatever the tech is at the time, it can be good to reconsider whether your views will have changed not on the technology, but on the larger pendulum it's riding.
