Great content for the upcoming drone wars and the inevitable tunnels that will be built for troop and matériel movements

Israel and the US have shown in Iran you need to dig extremely deep, otherwise you stand no chance against modern bombs.

But carrying bunker busters via drones is a lot more expensive than hand grenades.

Earlier quoted context omitted.

I think the “primal urge” to dig is just really seeking the endorphins of manual labor. Digging like that is especially attractive because there’s little planning (unless you’re making a tunnel like the subject here) and no material investment but the earth beneath your feet.

One of my sisters had four boys (and no girls) and during summers they would drive her crazy with their boredom. When they were about ages 8-14 one summer she said: go in the back yard and see how big of a hole you can dig. Wide-eyed they said: really? She said yes, dig as much as you want, but the only rule is it all gets filled in before school starts in the fall. 30 years later they say it was the best summer ever…

Perfect Venn diagram of man's urge to dig holes and the endless possibility and adventure of childhood Summer

What makes you think a tunnel would be safe? Just need to re-purpose this little guy: https://blog.sintef.com/digital-en/inachus-project-robot-sea...

But now you've forced your adversary to deploy and use "this little guy" on top of everything else they're doing. If you raise the costs high enough that they can't pay, you win. Yay!

Seymour Cray down in the tunnels, communing with the Machine Elves.

First person I thought about when I read the title.

If you haven't already, I would highly recommend this book[1] on Seymour Cray. An amazing read.

There's a lady on Instagram that goes by the handle 'engineerkala', who's been building a tunnel/mine below her home and learning the process along the way. I'm pretty sure one day the account will go dark when she's entombed herself a hundred metres below her living room, but until that comes it's a fascinating and extremely entertaining page to watch.
