For space elevators, to the best of my knowledge, there is no known material that can withstand the forces involved. Not even CFNTs.

For wormholes, we're getting so deep into speculation that the conversation doesn't even really matter.

That's how you get to cars.

Add more trains.
The trains now need to seat fewer people so make them smaller. Maybe 2-7 people per train.
Most routes aren't needed at any given time, so you might as well only run the train when someone needs it.
Rather than keeping the unused trains in a central depot, keep them at the departure points
We can't staff all these trains, and if the departure points are peoples' homes, then let's have the people themselves drive it
The network of destinations requires a TON of rail switches, and coordinating that is a complicated. Better to use a technology that doesn't require switches, like wheels on pavement.

Boom, cars.

So it really depends on what you're optimizing for.

The point I was trying to make was that tech bros are almost certainly trying to optimize for convenience, because they live in a bubble where thats what's important to them (or that's what has the highest margins).

As he said, rail is cheaper to maintain than roads. So the roads you replace with rail result in a net reduction of maintenance costs

We had good nationwide rail, and instead of expanding it, we dug it up and replaced it with nationwide roads.

So let's do it again, dig up the roads and replace it with rail.

Trains can be faster, safer, cleaner, and more comfortable. We can still have roads for the last mile, but trains for Intercity and interstate.

The problem is "perfection" looks different to different people.

If you're optimizing for efficiency, then you're absolutely correct.
If you're optimizing for convenience then shit like personal taxi drones is probably gonna be better.

I mean, currently both space elevators and wormholes (as transportation) seem physically impossible.

If we're not sticking to the realm of our current understanding of physics, then that opens the doors for techbros too, because we're in the realm of speculative fiction and things can be however we say they are.

I'm part of the problem, because I keep replying and giving you an audience, so consider this my last reply.

When someone is raising an issue, and you're considering if you want to expand or generalize the topic, ask yourself "will the person with the issue benefit from what I'm about to say?"
If they wont, and they're not hurting anyone, then maybe stfu, especially if you inhabit a position of power, in society, relative to them. If it's still important to you, then go start another conversation elsewhere.

In this case, they won't, and you probably do, and you insisted on speaking up here anyways, which makes you just like all the dudes trying to make this about themselves. You do not pass the vibe check.

I realize that the news show doesn't necessarily reflect the Dem, but you know it does

You just can't help yourself

Did my name give it away? 😏

But yes, I appreciate that sentiment 😩

One hell of a FUPA
