I used to do transcription for an online service. It was pretty fun; people uploaded all kinds of things, like interviews with celebrities, corporate meetings discussing products before they're announced to the public, and hilarious backdoor admissions of the absurd dysfunction of the american school system.
I wrote my own software for handling the formatting and editing, adopted all the best techniques that others were using, and even managed to outrace the floor as it fell out from under us. We watched from month to month as the pay declined and the difficulty of the work went up, because not only has the internet and its infinite scabs turned what used to be a fair salary into "gig work", but advances in speech recognition have more or less destroyed even that. Very sad. I hear the same thing happened to loom operators some time ago.
Notwithstanding the observation that technology has obviated entire lines of work in the past, online "gig" work is shit and if your inclination is to do honest work for an honest wage on the internet, you're going to be sorely disappointed.
The most important skill seems not to be anything value-generating like shoe-cobbling or carpentry or even programming, but "theory of mind" or straight-up psychopathy: the knack for trolling and knowing the right (wrong) thing to say to derail a thread and send normies into paroxysms of impotent flaming. If you understand how to push people's buttons like that, then you also understand what they're interested in, what they're afraid of, what they need, etc. Or maybe the thing that makes money isn't so much theory of mind as it is "reading the zeitgeist" so that you know what to dropship.
Don't be a tortoise in the race to the bottom!
