Yes.

I don’t want to agree because I like biking, but damn if “literally speed run” isn’t clever.

The kind of homes that would be a starter home for a working class family back in the 1950s just don’t exist anymore.
First of all, yes they do. They’re just mostly condos instead of single-family detached houses.
Second, even houses literally built in the '50s that still exist are expensive these days.

In reality, copyright is not ‘property’ and cannot be ‘stolen’ to begin with.

So this could threaten air travel for a huge region.
Also known as just “travel” because we’re talking about places with literally no way in or out except by plane. (Okay, and maybe hiking, dogsled in winter, or something like that.) That’s why somebody was apparently going grocery shopping by plane in the first place.

Trump didn’t have millions of people killed.
Yet.
Remember, the Nazis tried deporting all their unwanted minorities first, too. That’s why the gas chambers were “the final solution,” not just “the solution.” Trump still has plenty of time to match or exceed Hitler, if we let him.

- Comment on Would it be better to just have a lot of society be underground? 3 weeks ago:
Consider the following scenarios:
-
You start with a hill, then dig down into it and build a building such that it has a flat green (vegetated) roof at the original ground level.
-
You start with flat ground, build the same building on top of it, then mound dirt up around the sides to form a hill.
Two methods to the same result, right?
But now, imagine that instead of one building, you’ve got an entire city worth of buildings like that bunched up touching each other (no roads between them, just interior corridors). With scenario #1, you’ve still got to do a bunch of excavation for each and every building. But with scenario #2, you only need to do earth-moving around the perimeter of the city (if you even bother). Still the same result, but now method #2 is much, much cheaper.
I’m looking out over the Tokyo skyline right now and there’s every level of building. How do you get everyone to agree on the one right height?
This is a very hypothetical thread, so that’s the kind of issue that could just be hand-waved away as part of the initial premise. But if you want a real answer, that’s easy: “zoning codes.” Cities have absolutely no trouble exercising their authority to regulate building height.

Everything you think would be good about underground would be more easily and cheaply accomplished by building aboveground buildings that connect. (Or said another way, by effectively raising ground level to roof level without the expense of digging.)

I’m not convinced it wasn’t mostly dead before Steam, TBH. I mean I guess there was “lending” (read: copying), but there was never a “GameStop for PC games” the way there was for console games. And even the “lending” was somewhat curtailed by CD-keys and account registration before Steam existed.

- Comment on Why do tires have the width and diameter they do? 4 weeks ago:
This is merely a convenient approximation for properly-inflated tires carrying a load, not a hard rule rooted borne out during empirical examination. After all, removing a wheel from an automobile and rolling it along clean concrete leaves tire tracks that are full width, yet the tire will not substantially deform at the contact point because 20-30 pounds is not much of a burden. If there’s no deformation, then the contact patch is a line with a tiny area, which would wrongly suggest a ludicrously high tire pressure.
Sure, the tire itself has a certain amount of strength, but (unless it’s a run-flat tire, I suppose) it’s negligible compared to the load carrying provided by the tire pressure.
While bike wheels do act as gyroscopes – as do all rotating masses without a contra-rotating mass – this is not substantial to bicycle stability. If it were, kick scooters or e-scooters which have substantially smaller wheels but with the same physics as bicycles would be unrideable.
No, you’re overstating your case. First of all, I didn’t say that gyroscope forces were the only factor. Second, they are a “substantial” contributing factor. Your own wiki link agrees with me:
Several factors, including geometry, mass distribution, and gyroscopic effect all contribute in varying degrees to this self-stability, but long-standing hypotheses and claims that any single effect, such as gyroscopic or trail (the distance between steering axis and ground contact of the front tire), is solely responsible for the stabilizing force have been discredited.
The important part is the “gyroscopic effect… contribute” part, not the “solely responsible… discredited” part.
Remember, OP’s question was “why are the wheels big,” so the effect that’s relevant to discuss is the one that’s different between wheels of different diameter. And that’s the gyroscopic effect, not any of the other things that contribute to bicycle stability but don’t depend on wheel size. There’s a reason people generally don’t prefer things like Bromptons unless they really need the packaging advantages, and it’s because bikes with small wheels are (relatively) weird and twitchy to ride.
- Comment on Why do tires have the width and diameter they do? 4 weeks ago:
The pressure the tire exerts on the road is always equal to the pressure it’s inflated to. When the vehicle weight increases while tire PSI stays the same, the contact patch (area squished flat against the pavement) increases in size.
Bike tires are narrower than car tires because bikes are much lighter (so the contact patch doesn’t need to be as wide), and also because they lean into turns (so the contact patch can’t be wide). Bike tires are often larger diameter than car tires because they have more gyroscopic effect and thus make the bike easier to balance. They also make it easier to ride over bumps, but on a road bike (as opposed to a mountain bike) that’s probably a relatively minor reason.
I think motorcycle and ebike tires are a little wider (but still round in cross-section, so not like a car tire) for durability reasons because all the forces they’re subjected to are larger.
