As a general rule, if you're given a price for something by a company that specializes in that thing, and you think you can do better, you're wrong.
The creator alludes to this when he says not to ask how long it took him to build the machine.
As a corollary to this rule, if you've estimated your costs to do a job, and a company says they can beat it, you should probably do the job yourself. I bought a 3/4 ton jointer four hours from my shop, got a quote to rent a lift gate truck and a quote from a moving company/rigger. They were about the same. There's no way they can pay someone for a minimum of eight hours of time, plus cover their truck and fuel costs for what it costs me to rent a truck. The delta on their truck costs can't possibly be enough to pay someone good for eight hours.

Don't your rule and corollary disagree?
This is one of those things that's incredibly context dependent. There are lots of fat cat small companies out there who do easy tasks with thick margins. There are also jobs that are deceptively hard which it makes sense to hire out.
I usually try to err on the side of diy, but everyone has a different threshold on these things. Sometimes the economics work out when you don't count your time.

Probably? I mean, I knew I could get the jointer moved cheaper myself, because I have an idea what a competent rigger costs[0]. I just couldn't do it myself with that level of skill. Watch some YouTube videos of people doing rigging. The good ones are very good.
For the record, I didn't want to do the job myself because 1700 pounds moving in the wrong direction didn't sound like a bad time. I tried getting a quote to see if it was within the range I was willing to pay to not have to do it myself. When it came back at the cost of my truck rental, I couldn't see any way they could be charging enough to be good. Like, you wouldn't pay $15 to get a cavity filled. I would've tried getting more quotes, but the seller had a deadline.
[0] I went to an auction at a defunct furniture company. As the bids were finalized, a rigging company went around leaving quotes on the heavier machines for how much it would cost to move them. $700 doesn't move a lot of cast iron, and it certainly doesn't get it moved 4 hours away.
I think paper-folding machines are something of a lost art. They’ve been around for literally centuries at this point, but there are so many interesting and useful things that can be made out of paper. Everything from packaging to envelopes to origami.
I wish there were smaller, cheaper versions on the market.

This is very good work.
Those guys are very good, well funded, and have access to good CNC machining capabilities. They probably also know people who do automated assembly machinery. This was apparently about two years of work for a small team.

I like the part: "You might ask 'Isn't folding by hand faster than building all this?' Please don't ask that."
Showing a few of the crashes was a nice touch.
Having gone too far in trying to automate some projects of questionable value I can relate. I'm also impressed by what they are able to do, knowing people must help. Same with easy access to buying the parts they need.

Oh man how do you get a job doing this, it seems like the joy of programming but with haptic feedback

pretty cool. the first few minutes bored me, looked like a really standard industrial automation. then they got to the origami.
