Though it’s ridiculous to entertain the thought that one would pivot their career at the drop of a hat. Even just bumping into a tech stack will chain one to it as recruiters stare at yoe in a specific one and completely ignore anything adjacent, imagine doing anything more radical.
One can do it, but it’s a life changing, irreversible and likely damaging event nobody sane would take lightly. Absolute nonsense.
"I don't think it's reasonable to suggest that anyone who wants a job in tech should get one"
I understand your point, but this is the least bad world we're in. If you mandated no-firing or mandated year-long compensation for laid-off workers, you would be crushing the small business economy and destroying more jobs than you were trying to save.
