Brain/computer interface that completely simulates inputs which drive perceptions which are indistinguishable from reality. At least, that’s what is portrayed in the movie. I’m not OP but this to me seems far off.
Fair point and thank you for sharing it! It definitely does feel far off in that aspect. I suppose though, that if we are all trapped in a false reality it is impossible to know (without escaping the false reality) how advanced base reality actually is. I always interpreted the whole jacking into the Matrix thing, metaphorically, but with a literal interpretation the OP's comment makes much more sense to me. Thanks again!
I wonder how it avoids pipes stubbed up through the slab, or electrical EMT, etc. or how it avoids mistakes made during the rough-in.
What if the plumber missed a drain or supply by an inch? Guessing the robot doesn't adjust its outline. I.e. if a sewer stub is wrong by a few inches, the wall needs to be moved to fit the toilet, or the slab needs to be busted up and the sewer line relocated.
I suppose if it gets some of this wrong, it'll be obvious, and a human can correct it.
Realistically, if the plumber missed a drain or supply by an inch, it's probably fine to just move the wall by a few inches...but it ought to go back to engineering to verify that's so, and engineering can redraw the prints for the robot.
It's almost certainly not the layout guy's job to decide that the bathroom can be 3" larger than it was and the lobby 3" smaller.
I deal with this relatively often in a machining context - People complain that they'd rather just make simple parts on the Bridgeport manual mill rather than a CNC, because they can adjust on the fly with the manual mill but have to get the CAD changed so that CAM can adapt to the modifications. But when they make it manually, and a year later we need to ship out a replacement part or develop an ECO... if you did it by updating the CAD then the replacement part will fit. If you just freehanded it, the part will not fit.
I think the market is more towards industrial scale sites like data centers and Amazon warehouses and factories where equipment installation is happening right behind JIT layout.
Places where high precision matters and services aren’t connected to the endpoint at the slab. That’s not most construction because progressive refinement is how most things are built.
The concern is not the course, but the ability to adjust a layout due to deviations from the plan due to normal construction errors.
For example a pipe might not be in the location shown on plan for many reasons ranging from simple human error to a delta between the plan location when the pipe was layed and the time the robot got its data…keep in mind that when the pipe went in there was only dirt, not anything to accept ink.
But at that point it's back to engineering to figure out what to do (leave the pipe where it is and adjust around it _or_ move the pipe - possibly cutting concrete and perhaps untensioning/retensioning post-tensioned cables at substantial delay/cost) or move the piece of equipment that the penetration is serving.
One nice thing about automation like this is that the "as built" plans are more likely to be accurate because the only way to get "the computer" and "the robot" to stop squawking is to change the plans they are operating off of.
If this can't handle dirt surfaces, future generations/models probably will if there's demand. Perhaps such models would use spray paint/stencils or driving pins into the ground for marking purposes (or something more practical - I'm a software guy and this sounds like a hardware problem!).
My experience is with small residential builds but I would hope on large projects the location of each "unmovable" pipe/conduit etc that will end up penetrating a slab is already carefully verified before the next step is taken (such as placing concrete). Hopefully this is done with a total station rather than guys with chalk lines and tape measures. But a solution like this could reduce manual checking mistakes (of course, it's less likely to result in an experienced subcontractor noticing that the plan must be wrong because there's no reason for a conduit for 1KV electrical cables to come up 2cm away from a toilet trap in a multi-stall public bathroom - GIGO).

My experience is as an architect.
The CAD file isn’t the building no matter how much everyone might wish it were.
Even if the plans were the building odds of everybody using the same plan revision all the time is just about zero.
And most of the time, nobody is gonna pay for a super accurate as-built BIM. Because the point of the exercise is a certificate of occupancy.

I'm just one person, but I definitely am watching the local PBS over an antenna, and so do several members of my family (living in different households).
The local broadcast is excellent quality, I get a good signal to it, never any glitches, and I enjoy the local news and other programming too.
I don’t watch my local PBS over antenna much anymore, but it is great, just like you describe. Amazing what you can watch for free OTA, when you think about it.
As an American, having traveled in Europe a few times and dined out a lot, I much prefer the culture of just leaving me alone and letting me signal the waiter to come over when I need something.
I’ve been to the beach more times than I can count, over a lifetime living in Florida
. Loud music, yes, cars and especially big trucks, yes. But I’ve never seen people just pack up and leave their trash when they’re done. There are ample trash cans and they get used. Take this anecdote for what it’s worth.
Agree. Grew up near a beach and have been to beaches many times in different spots. Definitely have seen trash before but never as described, not to say it never happens. People are generally pretty good at throwing their trash away or taking it home.
