Or possibly autistic, I know someone who would come up with stuff like this and is autism-spectrum. Not saying that out of malice, either - if Archinist is we should be gentler.
How is creating a automated digging machine with semi-auto learning AI from literally nothing except the dirt on the ground and the minerals beneath the ground just as difficult as digging a really massive hole and filling it with paste?
This is really apples to oranges. One is *extremely* complex and probably impossible for any one person to accomplish on their own given any timescale, though given guaranteed infinite time anything is possible I suppose. The other is extremely labor intensive and would take a long time for one person, and though it
might be possible, it'd take so long as to make no sense. Personally, I'd rather
walk around the world than build a tunnel I have no real use for.
The other thing to consider here is maintenance - doing it yourself, large sections are going to fail or have problems before you can complete much of the thing. Even built well and to a reasonable standard in today's tech, tunnels need maintenance on a scale one person cannot possibly deliver. And to build a world-girding tunnel would require maintenance on a scale an army of people might not be able to deliver.
I mean, isn't that what most house-builders do, just dig a big hole and fill it with glue, wait a few days and then put things on the covered hole?
Only with toy houses on toy terrain, like with miniatures. Do you really think that is how real houses are built?
There's a little more complexity than that (running pipes & conduits, placing rebar), but essentially that is all you do for a slab foundation.
But pouring a slab and building on it is
nothing like tunnel building. If you want a channel or road, you might find more similarities.
Oh, and we
do have, today - in modern times, automated tunnel-digging machines. They're called
TBM's, and require a small army of people to keep operational. One got stuck under Seattle and had to be excavated by several hundred (thousand?) people over a year or so because it hit something it wasn't designed to cope with. That one moves 35'/day.
At that rate, building a tunnel around an earth-sized object would take ... (25,000 miles * 5280 ft/mile) / (35'/day) = 3,771,428 days / (365 days/year) = 10,332 years.
And another report says that they've logged 1,200,000 man-hours of work to get a few thousand feet, not including building the TBM. The TBM, which, at $80,000,000 probably equates to another 2-8 million man-hours. All that is
also not including discounts in the number of man-hours required for readily available products that automation, globalization, and an industrial base provide - things like steel, concrete, food, transit, etc. etc. As late as the 1900's, some 90% of the workforce was still farming, so doing it totally by yourself I'd think it'd be safe to assume a 99.9% inefficiency rate to take care of other stuff and just multiply all the hours required by 1000.
So for building a tunnel around the world,
your time is going to be the limiting factor, not the machine's. Let's call it (1,200,000 man-hours * 1000 (inefficiency)) 1,200,000,000 man-hours*66,000 (which is, 25,000 miles * 5,280 ft/mile/2,000 ft/man-hours) = 79,200,000,000,000 man-hours (27,123,287,671 work-years)
plus the time for building the TBM, and gathering all the materials that are used in the tunnel. But at this point, that doesn't even matter, we're talking 27
billion years to just accomplish this task.
