What advantage would hovering have?

No Street Infrastructure needeed to drive anywhere (kinda).

Ok, and where does the energy to consistently keep a weight in the air come from and is it really worth spending?

I know flying cars are some sort of futuristic trope, yet I cringe at it every time I see it. They always assume magical infinite power. In the real the reason we do not have flying cars is the same why you don't use a drone as a coat hanger at home: It is just more practical to use a mechanical solution that holds your coat for infinite time without any energy use or noise/heat emissions and it is much cheaper.

Lifting stuff against gravity is not free, but a piece of wood, a brick or a rubber wheel does a pretty good job at it. One way to do it is magnets, but that means you need even more complicated roads.

We are living on a warming planet where only the naive and the evil pretend that energy use is something only the poor have to think about. We all have to think about it.

What do you mean “we don’t have flying cars”? What are helicopters then?

Deathmachines that in their mechanical hubris angered the gods?

Aha, and which of the fundamental forces in our universe would it work with?

To play the advocatus diaboli: Violence is always condemned the most if it happens to a member of high society directly. The members many people on this very website picture themselves to be in the future. But if you structually starve half a continent to save a few cents on the dime or fire 30.000 workers that isn't only okay, it deserves a bonus.

If you call one violence but the other is okay because there are some layers of misdirection in between you may have to reconsider your ethics.

The sociologist Bourdieu has written about social capital and the impact of the ductus people aquire. Simplified this is why rich people of old money do not respect the new rich: Sure they have the money, but they do not have the taste, the manierisms, the language, etc. Being part of that part of society is more than just having money.

These details are a more important mechanism for social groups to differenciate themselves with than most people consciously realise in their day to day lives. Yet we constantly decide by minor details that someone does or does not belong to a group. Maybe a steelworker will notice by the way you talk that you never worked in manual labor even if you dress the part.

Most people tend to have multiple such learned manierisms, meaning you will walk, sit, talk differently with your male friends than in an academic setting or with your family for example.

So when young students enter university they undergo a massive adjustment phase where they relate their existing manierisms to the new manierisms they encounter. This is all in order to become and stay part of the group. There is of course a perception how one "is supposed to" write in academia and students try to emulate this to the best of their ability, which may or may not yield good results. Eventually they find their own academic language and aquired tastes.

There have been studies and those resulted in the less annoying backup sounds. These sounds are essentially harsh white noise, which has one significant difference to the beeping: it's level drops off differently with distance, meaning you can blast it louder and people who are really in the wrong spot will notice better it means them, while people who are not meant will not be annoyed or fatigued by it. Two noise sources combine different than two tonal sources and the human ear can locate broadband sources better than single tones.

This was developed especially for use in backup heavy environments like harbors where workers started ignoring constant beeps.

There's also another difference: beeps can reflect coherently off of surfaces, causing directionality confusion in a dense environment. White noise is much less likely to have odd interference patterns, maximizing our ability to localize the sound.

Right. It is all about the time you put in.

But one thing I like to stress is: You get to decide how to spend that time. Sure it is occasionally good to spend the time on "no fun" practise, especially if you feel your playing is lacking. But you don't get magically better results if you suffer while practising.

I'd argue the opposite: The person who has fun while practising will also learn and they will be inclined to put more hours in.

The most important ingredient is time. Just make sure you do something regularly. At the beginning you may just care about making anything that works and measures up to stuff you like, but the truest truth is that you can't start getting into a thing and expect your taste to remain the same.

As you learn more about the instrument you will learn more about what you like and it will eventually shift. There are people where this is not the case, but they are rare and they don't make better or worse music than others.

You may also start to notice more and more that the guitar playing was the simpler part in most music you like,the harder part was how it all came together as a band, how it was composed and recorded and mixed. Guitar players the world over try to compete with sounds that have run through microphones, mixing consoles, channel strips, mixed with other instruments and mastered. And some of them can't even hear where the guitar ends and where the bass guitar starts. So you have generations of guitar players chasing dragons and spending a ton of money on gear that gets them nowhere.

Gear isn't nearly as important as anybody makes it out to be, especially if you go your own way. And that is my recommendation: Go your own way. Sure copy others for learning, but develope your own sound, style of playing, your own music.

I always thought it was the musical energy of Bertold Brechts "Die Dreigroschenoper" that lead Hitler to power. /s

Just because two things are correlated in time, doesn't mean they are necessarily causally linked. Surely there are multiple factors at the same time behind the rise of a demagogue. In the case of Hitler the grievances of WWI played probably a much bigger role than economic problems.

Fair, but at the very least "hyperinflation caused Hitler" is a significantly weaker statement than "deflation caused Hitler", given that the former was replaced by the latter like 8+ years before Hitler's takeover.

Economic problems was a big part though, the 1929-33 great depression. It features heavily in political literature pushed by the Nazi party leading up to takeover. You know, like "Arbeit und Brot", etc.

Yes. And we should never forget that these ideas are just that: useful ideas. They may seem without alternative to most people, but that doesn't mean they necessarily are.

The deeper problem is that all these layers are still in use somewhere within Windows. Try to give your Ethernetcard a fixed IP Address for example. On your way to the correct setting (which has visually looked that way when I was still going to school) you will move through maybe 3 or 4 layers of UI paradigms like a freaking media archeologist. Each of the newer layers dumbed things down and kept the old thing as a fallback.

Meanwhile in MacOS they dumb things down without a fallback.

The only people who appear to make serious attempts at improving the usability of computers are the likes of KDE and other Linux desktop environments. It used to be the way that Linux was the thing you used despite its shortcomings compared to commercial OSs..

Surely they just want to avoid straining their database so they put some "performance hacks" into their database instructions that they Ab/B-tested to "work" for 90 percent of people or something.

Meanwhile they could have just returned the titles of all your videos you have ever watched as a list and let your computer do the heavey lifting by searching through that text on the frontend only to fetch thumbnails and such for the final matches. I have a webservice with a table of 4000 lines or more and I can search it quasi instantly on my smartphone with a simple Javascript script hooked up to an input field.
