I don’t see why the shareholders wouldn’t want his head on a pike as well.

I take it you have nothing else relevant to add to the topic. Cool. See you around.

Feel free to make up the difference by rereading those two sentences a hundred times. Maybe that’ll be enough for the point to get through.

4000 words? Oh please, that can be done in a hundredth of that: The laws of physics are constant, and more advanced technologies have energy requirements that must be met by preceding technologies. At the same time, each technology also has to offer enough tangible benefits to be worth pursuing on its own.

Feel free to name one or two examples and show how and why they’re incorrect.

We’re having quite a bit of trouble making that transition even with the benefits of a couple centuries of fossil-fueled industry. I find the idea of jumping directly from horse-drawn wagons to wind turbines and solar panels rather implausible.

I wonder if there’d be new fossil fuel deposits by then.

Probably not. Coal is basically trees that didn’t rot, and the reason they didn’t rot is that there were no microorganisms that could digest wood at the time. Between the evolution of wood and the evolution of organisms that could digest it, dead trees would just pile up on top of each other and sink into the ground under the weight of new layers of dead trees above them. Now that there are microorganisms that digest wood and dead trees rot away, new coal is not forming.

Oil does continue to form in some ocean areas where there is a layer of water without any oxygen on the ocean floor. Since these areas support no life, any organic remains that descend to the bottom (mostly plankton) remain unconsumed and eventually get buried and turn into oil. But it is a slow process. Estimating oil reserves is notoriously difficult, but it seems there’s about as much left in the ground as we’ve burned in the last fifty years. So in other words, four billion years of oil formation gets you about a century or two of industry. Since the Sun is about halfway through its lifespan, that means the Earth can potentially create enough juice for one more industrial civilization like ours. That’s assuming that those oil reserves are allowed to build up and don’t just get used up piecemeal by smaller civilizations arising in the interim. And also assuming that that final civilization is even able to make use of that oil, which is much harder to handle than coal (extraction, refining, transportation, etc.), without using coal as a stepping stone. And also assuming that no anaerobic microorganisms evolve that can survive on the ocean floor without oxygen and consume those organic remains, which could put a stop to oil formation just like wood-eating microorganisms put a stop to coal formation. Yeah, that seems like a lot of ifs to me…

there’s plenty of opportunity for a successor to us to reach the stars

No, there isn’t. We’ve already used up all the easily accessible sources of fossil fuels, so whoever comes after us won’t have the energy sources necessary to have an industrial revolution and will be stuck at a pre-industrial tech level forever.

this is rapidly becoming Reddit 2.0, just without spez

Becoming? Always has been.

So? Death from old age is inevitable too, that doesn’t mean I’m going to stop breathing or eating. All of life is just postponing the inevitable, but just because the inevitable is inevitable doesn’t mean we should stop postponing.

There is enough time for another intelligent species to evolve after us, the problem is that we’ve already used up all the easily accessible fossil fuels. That means they won’t have the energy sources necessary to have an industrial revolution and will be stuck at a pre-industrial tech level forever (or rather until the oceans boil off).

That’s cute and all, but it ain’t gonna be birds and deer who gets life off this rock once the Sun starts threatening to swallow it in a few billion years. We’re screwing up badly in the short term, but we’re the only hope Earth life has in the long term.

At least letting them talk in the name of free speech lets you know who the Nazis/fascists/white supremacists are

That’s great and all, but knowing who the Nazis are is just step one. Without taking additional steps, that knowledge is useless.

I just want to tell you, that Transhumanism probably won’t happen in our time.

Neither will the large-scale colonization of other planets. Sure, we’ll build small research outposts, probably some Helium-3 mines on the moon to power fusion reactors back home. But cities on other planets? Hell no. Old sci-fi was wrong. They used to think we’d be on Mars by the year 2000, in reality we even gave up on the moon. The kind of huge engineering we used to envision is way too expensive and pointless. There’s nothing on Mars that Earth doesn’t have, so why bother? Instead, we’re focusing on ‘small’ technologies like medicine, computers, AI. I don’t see us expanding beyond our planet in a major way until these small technologies eliminate the need for those large-scale engineering projects.

You could totally do a centrifuge on a moon/planet surface, you’d just make it a funnel shape rather than a cylinder; the downward gravity of the celestial body combined with the outward centrifugal force would combine into artificial gravity perpendicular to the angled surface. But I have a feeling we’re going to get rid of our organic bodies long before our space colonization efforts reach a level where such solutions would be necessary. Brain-computer interfaces are already being worked on, and we’re able to replace a variety of vital organs with machines even with our current tech. Once we can turn ourselves into brains in jars that can plug into a variety of robotic bodies, life support and logistics in space are going to become dramatically simpler and easier.

I don’t understand the obsession with colonizing other planets. The Earth’s gravity well is by far the greatest obstacle on our way to the stars. It makes absolutely no sense to me to finally claw our way out of one gravity well only to immediately descend into another one. The asteroids have all the raw materials we need, we should be focusing on zero-g industry and habitats.
