Hey Leon, ask GROK:

is building a tunnel across the Bering straight stupid?

Building a tunnel across the Bering Strait isn’t inherently stupid, but it’s a colossal challenge with questionable practicality. The strait is about 55 miles wide at its narrowest, with harsh Arctic conditions, deep water (up to 170 feet), and seismic activity from the nearby Pacific Ring of Fire. Engineering a tunnel in such an environment would push current technology to its limits—think extreme cold, ice pressure, and the need for ventilation over such a long distance. The Trans-Siberian Railway and Alaska’s sparse infrastructure mean connecting road or rail networks would also require massive investment. Cost estimates for similar mega-projects (like the Channel Tunnel, which is shorter and less hostile) suggest a price tag in the hundreds of billions, potentially exceeding $100 billion. Economic returns are dubious: the region’s low population (e.g., Nome, Alaska, has ~3,800 people; Chukotka, Russia, ~50,000) and limited trade volume don’t justify it. Alternatives like ferries or air transport are cheaper and more flexible. Geopolitically, it’s a headache—Russia and the U.S. aren’t exactly cozy, and China’s involvement (as floated in some proposals) adds complexity. That said, the idea has symbolic appeal: linking North America and Eurasia could foster long-term economic and cultural ties. Some studies, like those from Russia’s 2007-2013 proposals, estimated a tunnel could handle 100 million tons of freight annually, boosting trade. But the logistics, environmental risks (e.g., disrupting Arctic ecosystems), and political will make it a long shot. It’s not stupid—just wildly ambitious and likely impractical with today’s tech and economics. If you’re asking for vision, it’s bold; for pragmatism, it’s a stretch.

that sounds pretty stupid.

Yeah, when you boil it down, the Bering Strait tunnel’s a pipe dream that sounds cool on paper but falls apart under scrutiny. The costs are astronomical, the logistics are a nightmare, and the payoff’s shaky at best. It’s like trying to build a bridge to the moon—bold, but probably not worth the headache.

AI is the future.

If that can keep Elon Musk busy, I'm all for it.

All this does, is convince me that Putin is a moron, too.

Ah yes, Elon Musk, who’s famed for the quality of his tunnels

What I expect to happen is he'll promise it, get funding for it, do a mile of it, drop everything about it, report a higher wealth value, get into a suspicious one car crash

Personally? By hand? Please?

Given the distance required, what kind of economic payoff could be possible from such an expensive project? It's not like overland would be a cheaper transport option than Pacific shipping routes or anything. It's not just the Bering Strait being the problem with connecting the two after all, but the fact that there's nothing in NE Siberia or NW Alaska to bother connecting together. Are we making it for the polar bears maybe? Or are people going to drive the thousands of miles from Juneau to Vladivostok to sightsee?

That will be great when the first earthquake undoes the tunnel

Ok Bering Strait, so only geopolitically, geologically, and financially insane.

Like I kinda see a world where this is a good idea. If ww2 had sparked a long brotherhood between our nations and with europe a high speed rail across the tundras might be a good lower carbon alternative to flying and the Bering Strait is the most land based path between Eurasia and the Americas. Personally I'm not certain a tunnel is better than a bridge for this, but a few days train ride from cascadia to Moscow or Beijing would have plenty of takers if everyone was chill and could take a high speed train ride from Moscow to Madrid (and major cities in between) and from Beijing to Ho Chi Minh City, Seoul, Bangkok, etc. It would leave flying as really only necessary for Australia and island nations like Japan.

That's however not the world we live in, and Americans aren't clamoring to go to Russia or trade with them

Its probably a standard Musk project. Show futuristic marketing pictures/videos of round pod-style futuristic vehicles to billionaire oligarchs and clueless politicians with a buzzword salad, until the hype brings in investors. Interest in his companies goes up, the imaginary price of the company goes up, his imaginary gold pile gets bigger.

Then pocket the money and fail miserably delivering even a fraction of the promised things.

The tunnel in Las Vegas, Hyperloop, Cybertruck, Robotaxi (still in progress afaik) Tiny House, the electric freight truck (I don't remember its name), the various Mars projects just to name a few.

Sounds like it would make Alaska a lot easier for Russia to annex one day...

He needs to build a tunnel to life in prison

OK, but it has to be from the east coast going across the Atlantic, and you have to pay for it all.

He can’t even build one in Vegas…

It'll certainly make it easier for Russian forces to assist our military and ICE in rounding up citizens, so there's that.

secret invasion route

Giving it to Musk is a way of guaranteeing it will never get done. Still waiting for full self driving, Elon.

Could be neat if Detective Miller engages arthropod-robot form to offer people a ride down said tunnel, all the while reminding riders to check doors and corners.

Can we also have a tunnel dug to the moon?

Elon is smart enough to not ride his own rockets, he too will be smart enough to not enter his own subsea tunnel. Which is a shame.
