It's interesting how, in a lot of ways, it's reversing worker specialization. In an economy where it's difficult to pick a field and stick with it because the job prospects are unreliable, enterprising workers are left with little choice but to sign up for various services that, essentially, offer them odd jobs of various kinds. Maybe you'll work as a Lyft driver for 3 hours today, do some freelance plumbing for an hour or so, write some website articles with the time between jobs, rent out part of your apartment on AirBnB so you can make the payment this month, etc. I suppose it's possible some people thrive on this sort of chaotic life, and more power to them if they do, but let's not pretend that eroding the work culture and especially the worker/employer relationship model that we developed over the 20th century is somehow a good thing for everyone. It overwhelmingly benefits employers who want to get paid and don't care one whit for what happens to the people doing the work.
