Yeup. Interesting how the older LED bulbs are particularly bad for this (and in the UK, at 50Hz). More modern high quality ones seem significantly better.
In my case, I founded a company based on the algorithmic approaches I developed as an academic - www.blackfordanalysis.com
Folks who did their PhDs about the same time as me, and progressed through a couple of postdoc positions, are variously: science teachers, data scientists, product managers, quants, environmental analysts, software engineers, hardware engineers and industrial scientists.
In the UK, fewer than one in ten astronomers who take a first astronomy job post-PhD (usually called a postdoc) progress to a permanent faculty position. Those that do make the journey typically take about a decade and three to four fixed-term positions to get there.
The "paper" is here: https://arxiv.org/abs/2011.06090 but its analysis is not really something that you'd get published in an astronomy journal [speaking as a former professional astronomer]
