With a dash of Handmaids Tale and Starship Troopers (the movie).

To see how wrong any prediction would be for 50 years into the future, do the following :

Look back 50 years and see how accurate they were predicting now. I want my damn transporters, flying cars and jet packs. You can keep your 1984 though.

Look at all those millions of people dropping dead to vaccinations.

Oh wait! There aren't any. I know 30-40 people personally that got the vaccine that are just fine. The only people I know that died, did it before the vaccine was available.

I hear bootstraps cure anything.

As has been said, innovation would slow as the population declined but I think AI, robotics, and improved lifespan/health could make up for a bigger population. Hell, if you go far enough, immortal people (nano/organic) wouldn't need much in the way of support.

Any by kill off you mean starve, de-house and let die of curable diseases?

Thats right brother! God gave us this earth so we could do what we want with it.

Just coming to say that.

And also "Get off my lawn you commie hippies and your clean power"

The idea is nice but you forget, big studios have money. They can hire the best artists, voice actors and such. One guy in his studio apt isn't going to have the time and know-how to compete with that. A more modest, and I assume nimble idea, would be to get a tight gang of like 6 people, each with their own specialty.

Not enough people, and certainly not the 1%, care enough about this to actually do anything about it. The 1% are in charge. They own the politicians if they aren't those people already.

Taking 3 examples : The disappearing Amazon Rainforest, retreating glaciers, and the great barrier reef dying off. Suppose all these things are either a coincidence or inconsequential? This is not mentioning the many mass extinctions taking place, rising sea level, or average global temperature rising.

Again, none of this matters to me except academically . I wont be around when the effects really start hurting humanity. I feel a little sad that this is happening but I expect it from humanity. We are much better at reacting to the present than planning for the future.

Sorry I'm not going to be around when the ecosphere collapses. Our great grandkids are in for a wild ride.

What about when some idiot creates a virus/bacteria that destroys all Petroleum products? How you gonna produce energy then? No plastics, and what else?

Lived to the ripe old age of 24

Its not gay if its underway.

Wrath of Khan style?

I love to think about the potential for good but when is someone going to target a gene for say, dark skin pigment, and attach a bad gene like say infertility.

Here's a better question.

What doesn't cause a war between humans?

This! ^^^

In 50 years half the state will be underwater.
