In 500 years the world will either be horribly overpopulated or there will be few humans left.

How do you perceive the residents of the Planet Earth of 1519?
That's how people in 2519 will perceive us. Though, by that time, large numbers of them will be living on other Worlds.

Sometimes I wonder if we’ll get another 500 years… Perhaps they’ll consider us one-time ‘gods,’ apparently having built structures that tamed rivers and defied gravity!

Or (and hopefully), we’ll be looked upon charitably as still learning.. One sad aspect ‘of now’ for me is I/ we’ll be lumped together with the average idiots in a category called something like, still worshiped gods... Hopefully, by then my molecules will have become so intricately incorporated with new life that I won’t know, or care

Inconsiderate, self-obsessed, dumbfucks I would suspect.

I know I would from that vantage point!
