The takeaways I remember about that: A good producer matters, a team of a least three people does better than one or two, and experience shipping stuff matters.
Private property law allows owners to enforce their own rules(to a point). This both explains the private control over the train and tracks and lends weight to the possibility of being kicked off the train, as it is justified in terms of disruption to service and resulting monetary losses. To wit, a positive externality of transit service is economic gain from the population having improved market access(more goods, services, workplaces within reach). The transit company does not realize these gains, the public does. The company's enforcement of rules is guided by the premise that some amount of security and order is necessary to achieve its service goals.
That way, different projects can have different versions of everything, and system environment is only important to the synchronization step - trivial to fix up if needed, trivial to copy between machines.
We're just all so used to schools setting up all the obligations for us and monitoring everything, that taking a more freeform approach is unsettling at first.
I see the process as not being different from what's needed to do the writing - compiling notes and sketches and outlines into a coherent narrative.

If you want the flexibility to cover every avenue of "i and my family have a shot at making it," you either arrive at a combinatorial explosion of complex needs-tested programs, or basic income.
Since every program you make will induce some unique form of leakage, corruption or freeloading, the expectation of BI is that it limits that to "some people do not have the personality to manage personal finances, and will always be broke in any given situation." But that doesn't take anything "away" from people who can be responsible - they will in fact be insulated from the drag-the-family-down dynamic that prevails in the deepest instances of developed-world poverty, because they get their own BI at adulthood and can just run away from the situation without severe risk or hardship.
From an overall technology standpoint, both engines should prove worthy of study given the radically different focus.
For example, people did not go from buying 1 car to buying 10 cars and then 100 cars - most of us hit saturation somewhere between 1 and 2, and stayed there. Similarly, the average speed of our cars did not increase at an increasing rate except in the earliest years of automotive technology; we have a "highway maximum" between 50 and 70 MPH, and a "technical maximum" in the high 200's range for production cars which do not rely on rockets or other not street-legal tricks (a quick search brings up the Hennessey Venom GT at 270.49 MPH). Likewise applied to fast moving vehicles as a whole, including supersonic aircraft and rockets, we've already brushed up against vehicle weight and power density limits that slow the rate of improvement in acceleration.
Applied to the Moore's Law measures, that indicates we have a "endless sunset" period ahead of us where we'll still get more doublings of semiconductors, but they'll come increasingly slowly as more fundamental innovations become necessary to realize them.
What we don't know is whether there is a logistic curve on technology as a whole. Belief in the Singularity is premised on this not being the case.
I don't think this is doom and gloom for accessibility, though. The future is in general-purpose assistance technologies that mediate any application. You can smell it with the new work in ML. It is not here now, but as with everything in technology, by the time it's mature and widely available, it's nearly obsolete.
If you actually code some audio DSP(and I do), you quickly learn that there are a lot of ways to color sound that aren't quantified except in a very broad statistical sense, but are measurable in audition. What digital is very good at is the basics of reproduction with a (statistically) uncolored result. At artistic effect, it is somewhat more limited; a lot of compute time and engineering has to be thrown into reproducing some straightforward analog world things and model accuracy still has room for improvement even now.
If you want to quibble with the video, do so on its terms. It isn't saying that digital is better, it's saying that digital is better at a very specific task.
"I have a question" in speech DOES have a purpose, which is to prime listeners to enter conversation mode instead of stopping you to say "what" after you've said two words. Of course, I've seen people who are on the ball and impatient still get testy about that convention.
Edit: the most infuriating experience I've had in recent memory is a friend who will consistently spam his shitposts over IM without warning, but when it comes time to do business will say "hi" or "are you there" instead of asking the question.
But the consent of the people does exist, as a mass body. It takes quite a lot for a critical mass of them to decide that the government is no longer legitimate and disorder would be preferable, but if they do, the government is pushed into crisis. And when governments make breakthroughs, it's in the moment of crisis where leadership is forced to either make a big concession or be pulled down by the mob. In between crises, the status quo sticks and politicians jockey for position within it instead.
What that never translates to is the individual who sticks out of the crowd, arguing for change, getting special treatment. At all times, even in the era of post-Enlightenment reason, they are viewed suspiciously, because good enough is good enough, and they might just be another "bad guy" (criminal/barbarian/spy/rebel/etc.) trying to pull a fast one. They get no credit; as with business and innovators vs. fast followers, it's the people who come afterwards, using more polished rhetoric and building existing small movements into large ones, who tend to turn those ideas into reality.
That said, if your functions are pure functions, they won't contribute much to overall complexity. It's a much different situation from having a do_the_thing() method that does some mutability magic.
Likewise with the new generation of small EVs, visual processing, and networking, you can scale the infrastructure for everything more exactly, with a variety of vehicles of different sizes and carefully synchronized transfers, instead of forcing car traffic into primacy.
From that perspective it's easy to see why PRT was a hard sell - it's less flexible than a car and it doesn't have the capacities of light rail. The automation part has stuck, though.
The important ones like conventions surrounding replies are weird artifacts left over from the early days of the product. Twitter bottlenecks quickly in lengthy conversations amongst multiple parties and you really have to carefully respect the social dynamics it creates, or people will just block your rude self. If there is one place where the product could use revision, it's in improving average case conversation quality.
Regardless, I like having end points on these projects because they give you a sense of relief at the end. It also helps to aim for low frequency with each goal so that your daily schedule isn't rigid - a 15 minutes per day investment is actually quite a lot.
But what you can't do is create an "all-around" city where every transit option has equally low congestion. People will show a preference for whichever mode they got used to, and fill the others only as they hit their tolerance limits - not because one is faster, or cheaper, unless it's substantially so(and then congestion will arise to even the odds). This typically manifests today in a city crowding the highways but leaving the buses empty. New construction will mostly be used by newcomers unless there is some disincentive to drive, like downtown congestion charges, reduction of parking, smaller roads, etc.
The bus lane capacity thought experiment equates velocity to throughput. This is obviously wrong; while a bus interferes with some traffic, it also pulls more people into less space. Multiply that along the whole route, at high frequency, and you end up with geometric efficiency. A bus may go at a third of the speed, but it carries easily 10x as much as a four-seater, and bigger buses could hold even more. At the peak hours, congestion and slow speeds are assumed and vehicle capacity starts to matter for delivering the most commuters home in a timely fashion.
Then consider the network benefits of running more routes and connections at higher frequencies. Public transit has to hit a certain critical mass of densities and destinations before it really takes off; most of the US today, being heavily suburbanized in the mid-century fashion, does not enjoy this. But the New York City region got there, and several other metros are showing signs of moving in this direction. Access to transit is implicitly improving now that we're in the era of electric rideable vehicles and people making their first/last-mile connection can go at 10-15 MPH on whatever weird gadget they want without breaking a sweat or having to find lockup space. Capacity becomes a complicated equation with all these factors.
But with the Web, the genie is truly out of the bottle and nobody can put it back in. It's the same shitty platform as ever, with more and more kludges added on. So we look to automation for a silver bullet, and by sheer force of numbers we've succeeded in building something that Just Works most of the time and requires deep technical skills to fix otherwise.
