In the past, "on-demand" simply related to instant television episodes. Now just about anything can be done with the click of a button: in addition to the ever-popular rideshare apps like Lyft and Uber, users are ordering laundry services, massages, even dog-walking from their phones. You can even arrange for someone to wait in line for you with services like Task Rabbit.
This "gig economy" created three types of jobs almost overnight:
Side-hustlers (or full-time hustlers) who drive, walk, massage, or stand in line for the users as a source of income.
App companies being pitched, created, and invested-in at lightning speeds. They need employees to build the technology (what language should it be built in?), optimize it for the best user experience (how seamlessly can we get the user through the shopping cart?) and ensure that it works correctly (constant updates in phone technology means constant quality assurance checks.) Software developer jobs will grow 18.8% between now and 2024, according to the BLS.
Delivery services are at an all-time high. Shoppers are spending a record amount of money online. Every item purchased online needs to be delivered - by plane, by train, or by truck or car. Each of these delivery vehicles needs to be built, serviced, and operated.
