What is the human race end game?

How do you turn rust back into iron? Is it easy? Can it be done without modern technology? Who knows how to do it? Did they survive?

it won't all be rust, and it'll be discovered the same way it was discovered the first time round.

if anything you might find instead of the bronze age it might be aluminium, melting and casting old engine blocks.

question is, what is this disaster that we're somehow surviving without the use of modern technology.

Everything online would go quickly. Digital hard copies would last longer, but would survivors have access to them and have the equipment to read them and have the electricity to power the equipment? Paper generally doesn't last anywhere near as long as parchment, so even paper copies are temporary. Even assuming that the information is available to some groups of survivors, how could they make use of it? You mentioned merkava. I looked that up - it's a top quality modern tank. The blueprints for that would be of little use without the facilities, infrastructure, supply chains and power to run a suitable manufacturing facility.

it would take several generations for people to forget how to read/write, put fuel in a generator, operate a pc etc, and the survivors as a group would more than likely have a range of professions each with their own knowledge base, at least assuming the group is large enough to sustain/repopulate without resorting to incest.

the merkava thing was just a specifically israeli example of something technical, point is any old libraries around are going to have books with plenty of knowledge, sure you ain't starting straight back building cpu's and messing around with particle physics but you're gonna be skipping big chunks of historical misconception like thinking all medical ailments were the work of the devil rather than drinking dirty water.

Maybe population will decline voluntarily. More prosperous countries often have a downward trend in population. Maybe if things go well population will reduce to more sustainable levels quickly enough, in combination with more sustainable use of resources and acquisition of offworld resources (e.g. automated asteroid mining). Maybe. It seems a stretch to me, but humanity does have form for pulling last minute solutions out of the air when problems become impossible to ignore.

i'm not convinced that on the global scale that will work. it must be remembered that the way we've set up the world is the prosperous countries are leaning on the labour and sweat of the less prosperous (who work their way up to becoming prosperous shifting the load onto someone else) and someone always has to be bottom of the pile.

but then there's not much precedent telling us which theory will hold true, however as good as humanity is at taking drastic steps when there's no other choice, we're equally as good at forcing drastic choices by kicking the can down the road. the hope we never do that so long that by the time we realise it's already too late.

Maybe this is one of the great filters in that hypothesis explaining the Fermi paradox.

I actually think the opposite would happen. If we ever got to the point where people just didn't have to work. Child births would go up rapidly. The decline in childbirths is more to do with career progression rather than anything else. When you look at the super rich they have a lot of offspring whereas us normal folk who have to work have maybe 1 or 2 kids.
 
Warhammer 40k is probably not too far off where we will end up ie. hive cities, protein farms etc. xD

I'll opt for dreadnought, being eternally encased in armour and being able to falcon powerfist punch some orc burnaboyz would be mint.
 
Genetic engineering. Once we do that we aren't human. Duh.
I think there wil lbe a combination of genetic engineering and also robotic augmentation eventually, resulting in vastly longer lifespans and an ability to survive in harsher environments. At that point colonisation of other planets will be realistic.
 
Well thats true anyway but I read it as the human race will die out... is that what you meant? I definitely think that...

Absolutely, the universe itself is finite and will end if a few septillion years. However our solar systems sun will become toxic to life in the next couple of million years as it ages and the planet will be stripped of all life on the surface. Unless we can bugger off somewhere else by then we are doomed. Ultimately though, we are also doomed by the end of the universe. I must go to the restaurant there.

I think its more like billions or hundreds of millions than a couple of million but irrelevant for you and me (and our kids/grandkids etc)

Current thinking is the Sun will start to get much hotter as it ages. It currently thought that in around 2 billion years the heat of the sun will wipe out life on Earth. Then in another 3 billion years the sun may swell up to engulf the Earth's orbit but life would be well gone by this time.
Life? Don't talk to me about life. Here I am, brain the size of a planet, and they tell me to take you up to the bridge. Call that job satisfaction? 'Cos I don't.

I think you ought to know, that I am feeling very depressed today.

Edit: I cant count.

Every time you try and operate these weird black controls that are labeled in black on a black background, a little black light lights up in black to let you know you’ve done it.

I wonder what happens if I press this button?
Don't
Oh
What happened
A light lit up saying please do not press this button again.

5.4 Billion years to Red Giant phase... I think your 2 million years may also be orders of magnitude out too ;)

a) We are all a simulation (maybe run by the mice to answer the ultimate question) - once the simulation has run its course it gets turned off or changed till it's not something that could be recognised as what it once was.
b) we keep growing and evolving, eventually realise the singularity
c) doesn't matter as it won't happen in our lifetime, we survive and procreate move forward through time slowly changing and evolving till someone messes up and kills us all

so yer - glad i won't be around to see it :D

To find answers to the big questions

Why are we here?
Who created us?
How does the conscious mind work?
When can I get a graphics card for a reasonable price?
 
Genetic engineering. Once we do that we aren't human. Duh.

Or are we? It's the ship of Theseus again - if you replace every part of something bit by bit over time, is it still the same thing? We wouldn't be homo sapiens, but would we still be human?
