Readit NewsSpeak for yourself. My ancestors pre-industrial revolution were half starved tenant farmers making a subsistence living on too small plots of farmland in colonized Ireland, subject to random slaughter when the English changed their plans.
Now, our extended family is prosperous in the US, Australia and Ireland. We’re taller, healthier and mostly in professional or skilled trade jobs.
The past is often seen through a sepia tinted idealized slant. The past was full of suffering and brutality. Even warfare was just as brutal - in ancient times, Caesar slaughtered 1-2% of the global population in Gaul. In the 17th century, marauding armies picked regions cleaned and left thousands to starve.
War, disease, famine were the norm for eras past. For those who lived during those times, I reckon their level of perceived suffering was no more than ours today. Humans are tragically skilled at adapting to new standards and shifting the threshold of struggle. People today get frustrated over a delayed plane departure likely just as much as people in the past were over a storm delaying their caravan by a few days.
As much of a proponent of technology as I am, I often reflect on whether we are truly bending the arc of suffering in a positive direction, or if it has remained far more constant than we’d like to believe.
And while you'll absolutely learn some things and find yourself excited about some ideas in those couple years, you will forget almost all of the stuff your learned within a few years of graduating because you won't be continuing to get your hands dirty and won't be building on the knowledge. Technical knowledge does not "stick" if you don't use it.
If you're a hungry learner and have the free time and money, you can go back to school for whatever you want. This sounds adjacent to your work, at least, so that's something. But remember that formal education is only the first and smallest step in learning a technical discipline, and it sounds like you want to continue PM'ing rather than transition to a technical IC, so you won't be continuing on the later steps.
If you're just trying to be the best technical PM you can be in your industry, there are almost certainly far more time/cost/stress-efficient ways to do so.
