I think that it will be an excellent thing if "crowdwork"/"gig work" becomes much more common, and becomes recognized by most as an inherently viable way to earn money.
I think it would be great if some people earned all their money this way, and some people earned some of it that way, earning other money by developing freelancer profiles or by having standard "W-2" "jobs".
I think that current trends make this viable. At the same time, people with W-2 jobs are much more controllable. It is also true that W-2 jobs routinely offer all sorts of "benefits" that do not come to other sorts of workers. In the present day USA, people tend to regard "having a job" as crucial, but I think that a big part of this is that "having a job" provides benefits like health insurance, etc., that are not logically connected at all with employment or doing work to earn money.
If I am right, then some sort of alternate social safety net, like UBI, should be seriously debated. At present, this seems supported mainly by "socialists" and a few "techbros" who are looking towards the future. I am hard pressed to see how UBI would be any worse than the bureaucratic hodgepodge of public welfare programs that now exist. To some extent, "Obamacare" was sold as something like UBI that would enable freelancers, etc, to do their own thing, but... maybe I should just drop that topic. To be honest, I am very sympathetic to the basic impulse, but I think the reality has been disastrous.
As to why I think crowd/gig work may have inherent value, I have three points right now: 1) it can free workers from dependence on particular employers and allow them to engage with the wider world as they see fit; 2) it can allow workers to pursue multiple options at once, while still earning money; and 3) it can allow workers to separate the task of earning money from the pursuit of whatever actually matters in life.
Also, the basic viability of crowd/gig work, from the perspective of employers, is only going to increase, so I think it makes sense to consider how to make it work.
I will give this more thought...
