Something to think about is how much the anthropic principle plays into things. Here is how I think about it: assume everything that happened to Earth was required for intelligent life to develop.

So, you need a planet with a large moon. That can only happen if a planet that was just the right size hit us during formation. That's pretty rare.

Assume you need a fairly significant axial tilt. Assume you need a rotation speed that gives a day length that is not too long and not too short.

Assume you need just enough water to cover more than half the planet, but not so much to cover the whole planet.

Assume you need a large Jupiter-like planet to shepherd asteroids.

Assume you need periodic large asteroid impacts every few hundred million years. Not too big, just enough to "reset" life to give other species a chance to develop.

There are probably a bunch that I'm forgetting about... But I think intelligent life is harder to develop than just needing water and oxygen on a planet.

Honestly, I would still be doing what I'm doing, except I would be writing the software that I want to write, instead of the software that some company wants me to write.

And the AI assistance would help my projects go way, way faster.

I don't really know how people survive without subscriptions on Reddit. It allows you to curate your feed, so you aren't inundated with the stupidity of the default subreddit list. Once you have set up your subscriptions (and most importantly your unsubscriptions), Reddit is a completely different experience.

Going back further, it originated from a cloud of mostly hydrogen and helium gas.

All evidence we have so far points to heat death. Big bounce is highly unlikely given what we know. Dark energy is pushing the universe apart way faster than anything can hold it together.

Sure, if you brought the sun close enough, you would start to float up towards it instead of being held down to the earth.

Of course, the entire earth would be ripped apart as a result of this, but you would definitely feel light on your feet as everything around you was being destroyed.

Yes, unfortunately not enough to affect the scale when you are weighing yourself.
