No, Y2K would have been catastrophic.
But a shit ton of people out in a ridiculous amount of work and everything was updated.
People concerned were fucking "doomers", they were the reason shit didn't go terribly.
But because rational.people helped everyone avoid the consequences, idiots think we could have just ignored it and had the same result.
It's fucking ridiculous you didn't learn this lesson from covid even if you're too young to have experienced Y2K
