Indeed, the statistics they provide aren't as significant as the headline suggests:
> Hundreds of thousands of Americans are striking out on their own...
For reference, the United States has around 160 million employed people. 0.1% of them moving to freelancing might be significant, but is it really a new era? That was happening on the regular well before COVID.
1 in 1000 people striking out on their own doesn't really explain the "ongoing shake-up in the world of work" like they're trying to suggest.
