It's 2024 and it's not looking good for us!

You need to eject yourself from a collective-mindset, and just find whatever specifics, as far as lifestyle, for yourself and your family that will bring happiness and prosperity, and don’t concern yourself so with everyone else. There are plenty of options, and I’d say if you have the tools to post on MovieChat, you are certainly more advantageous than people drowning in jungle swamps or starving in vast deserts. You don’t need to worry about assimilation of others like the Borg on Star Trek, and don’t try to be the assimilator yourself. Zero chance of humanity extinguishing themselves.

The Time Machine is about as fictitious and fantastical as a story can get. If you’re scared, please sober up.

Specifically, why do you think the world is in such a worse state than it was, say 40 or 50 years ago, much less 10 years ago? I think you'll find you're simply more informed of global problems, than there are actual MORE problems

Keep in mind that when you're watching (or even reading) time-travel stories, much of what you see in "the future" is speculative fiction. Since we can't predict the future, writers of these kinds of stories mostly just make things up, or go on what they know of human nature and what they're seeing happening in the world at the time they were writing it.

Plus, the writers had to have a more up-to-date explanation as to how the world got the way it did 800,000 years later, because H.G. Wells' explanation wouldn't have really registered with modern people as it did Victorians who read his book.

Watch this clip and tell me what's different now:
