Your larynx isn’t really a limb… But nah, its an evolutionary artefact. In primordial fish it’s a straight line, but then the head moves, a neck forms, etc etc. and the nerve can’t detach and move over, so it gets longer wnd weirder.

Do brick or stone roads last longer than asphalt or concrete roads?
That’s a solid “it depends”. And in this case, it depends on the definition of “lasting” and the definition of “road”.
Klinkers are near immortal, but they’re laid on what we call a “street layer” of 3cm of compacted, specifically graded sand, on top of some 25cm of less expensive sand. That sand can shift, compress and ruin the stability of the bricks. That usually happens due to heavyweight transport, or external factors (settlement of the soil underneath, tree roots, etc). If you run just passenger cars in a suburban area on steady ground, it could last 50 years. If you supply your stores on a road like that, it’s more like 10 years. But you can remove the brick, regrade/replace the sand and rebuild it from mostly the same bricks. Concrete bricks don’t last as long, and they break more when removed/packaged/relaid, I don’t really know the numbers.
Asphalt is different. Assuming we’re talking about a road that could also be made in bricks, asphalt has a surface layer of some 3-5cm, then between 10 and 20 cm of underlayers in layers of around 5 or 6cm. Then some 20-30cm of gravel, and up to half a meter of sand. That top layer lasts something like 10 to 15 years, and it suffers most from frost/thaw, UV light, etc. You don’t have to replace al of it at once though, you can patch it.
The underlayers generally fail due to traffic weight, but that can be 2, 3 or maybe even 4 cycles of surface layer replacement later. Generally, for busier (non high-way) roads, they replace the surface layer twice and the third time they do parts of the underlayers, or all of it, depending on damage. Asphalt can be 80 or 90% recycled though, but it takes quite a bit of heat (something like 3 to 6 cubic meters of gas for each ton of asphalt).
So, all in all, not all brick roads are equal, not all asphalt is equal. And “how it lasts” is a complex question too. It’s also a tough comparison, because we generally don’t build roads for the same purposes. If it’s very busy, we usually don’t use bricks.

- Comment on The internet kind of sucks right now 1 week ago:
People these days dont realise that confidently incorrect people pre-exist facebook.
It’s different though.
If you were a flat earther in 1982, you probably would have a weird self published “newspaper” by someone 4 times a year, and two or three books and no platform beyond literally shouting on the street at people who all considered you a moron.
Nowadays, if you’re a crackpot, you can instantly find 17.000 other crackpots who will happily not just confirm your idiocy, but make up fake stories to support your bullshit ideas. They will also drag you along by pure crank magnetism into other bullshit. You can spread your bullshit far and wide, and since people are automatically served with similar content, you’re even likely to find other idiots like you “in the wild”, which is actually an algorithmic bubble.
Before, nobody you met in real life would agree with you. Nowadays, everyone you “meet” online agrees with you.
So yes, confidently incorrect people have always been there, but not in these numbers, and rarely to this level of confidence. That’s why people react to vehemently, they rarely ever reach outside their bubble. Your ideas that the world is round aren’t the general concept to them, they hear from flat earthers every single hour of the day.

No.
Or at least, not always. I’m in plenty of online groups with people who have shown their trustworthiness and expertise. They are people with a reputation.

My problem with it is that in Ye Olde Times before 2022, if you needed some info on, I dunno, amethist cutting blades, you joined the crystal geode cutting forum and maybe became a contributing member of the group.
Now, you ask chatGPT, and contribute nothing.
- Comment on anons brother has some strong opinions 1 week ago:
Oh yeah, klinkers (if they’re baked clay) or the much less inspired sounding betonstraatstenen (concrete street stones) definitely have their benefits, but that video really skips over what a literally backbreaking job it is to tile a street like that, or how slippery these stones get when wet (less so for concrete or textured baked clay)
Of course, running asphalt over a street like this gets you the worst of both worlds, and its begging for potholes since the two materials match up really poorly. You do occasionally see it in the Netherlands on old roads on top of dikes that were “modernized” in the 70s and 80s.

I’m sorry, is this asphalt over baked paving stones? And if so, why?
Or is this a pothole filled up with stone? And if so, why?

Trying for academia turned me off of chemistry so hard, I even started to hate my later corporate job doing research.
Though it did get me into regulations and safety, so it all worked out fine. If things had been different, they would have been different, but academia was a massive disillusionment for me.
It sounds weird to say that doing research for someone’s increasing personal wealth was much more enjoyable for me, since the funding was just there, and I didn’t have to teach students or write grant proposals I never wanted to complete.

I have a PhD because I thought I wanted to go into research. And while I loved research, that didn’t come close to cancelling out how much I loathed all the non-research shit you need to do for funding and keeping a job.
Then I went from academia into corporate R&D, and realized I basically started to hate doing chemistry in general. Mostly because it reminded me of all the stuff I hated.
Im now super happy as a safety consultant, and my PhD sometimes helps in convincing people that I do in fact know more than them. It also covers an ugly spot in the wallpaper, a purpose it fulfills much more frequently.
