Do you think the promise of the FIRE movement has severely been hit due to a black swan event like COVID-19 which removes the ideas of stable dividend income?

Dividend income is not the only way to achieve passive income.

Also, continuing to work and earn income even in retirement shouldn't be looked down on as it's a good way to keep yourself sharp and relevant.

I rather see the over reliance on dividends as being exposed by covid 19. Fire doesn't have to rely on dividend income at all. It just one way to have a stream of passive income. We can consider active income in meaningful work too. I see covid 19 expanding the scope of fire movement.
