“But will they be good jobs?”
I suppose it depends on how each individual defines what is a “good job.”
That’s the thing about work — whether you’re talking about the gig economy, freelancing, full-time, part-time, or whatever else. The individuals who choose the work are the sole arbiters of what they determine to be a “good job.”
That’s the beauty of the world we live in today. We can all determine for ourselves what we consider to be the trappings of a “good job.”
For some, it is location independence. For others, it’s flexible hours or the ability to work the midnight shift (or the day shift, or shifts that span multiple days, etc.). Some people prefer the opportunity to work alone, while others like to function as a member of a collaborative team. There are those who prefer pounding keyboards over pounding nails.
Bottom line: What constitutes a “good job” is in the eye of the beholder.
