I was aspiring to skill up my JavaScript this year and after a few hundred hours have ended up pretty demoralised, realising that the amount of learning required to be a good JS dev in 2020 (at least where I am working atm) seems enormous, and to be frank I'm too old to be wanting to put in evenings and weekends merely to remain competitive. As a consequence I suspect I may well seek to switch back into support, presales or consultancy, all of which I've done in previous roles, and which seem to be somewhat less competitive than straight dev but still rewarding and reasonably remunerated. Overall my feeling is that unless you're pretty rockstar-ish the cost/benefit of being a dev just simply doesn't pay off in 2020, at least here in the UK.
