Actually, drone delivered LATTE COFFEES are probably at the top, of any consumer business you might start, as an alternative to electronics...
Just as many other replies, here, I express frustration and look elsewhere, but end up sticking with Electronics as a first choice, trying to make my (rent).
In 1995, after industry lay-offs, I determined to look elsewhere... But by 1999 I was back at it, doing my best to garner resources and focus (on business documentation). Simultaneous, though, I did develop some non-tech industry usefulness: I did security monitoring (retail), private security (house and pet sitting), even Pet Walking. Non of these informal gigs involved any certification / licenses.
I've even taken to heart, a Clint Eastwood movie, when he was DOWN, I mean really down, he used that time, practice, practice practice. What I mean is, he recovered from injuries, while getting his skills upgraded, privately. THEN, as troubles eased, he was back: stronger than ever, and with some new tricks.
(Course that was cowboy stuff, "The Good, the Bad and the Ugly", or one of the other 'Spagetti Westerns'.
I do remember in some past social disasters, the government went after those that illegally gouged supplys, (food) in wake of disaster. They 'shoot looters' used to be a thing said...
But this is getting too wordy. I did want to say, I could hire 3 'Ricks' right now, to build / research stuff. Everything from frivolous consumer products (pocket shower) to nano-tech and even Bio-tech musings...
I just can't pay.
