Just because it is Microsoft's tool doesn't make it my preferred tool. Actually, just the opposite.
What is totally useless is to do several things in parallel. The old story of Napoleon being able to dictate a letter, read a book, have a conversation and lead a battle all at the same time is simply bullshit. Had he done so, he would had sucked at all of them, in parallel.
While your Cessna needs to run its engine on a substantial fraction of its rated power (typically 60% or more), any decent car will only need low double digit kW to cruise. Comparing the rated power is utterly misleading, and your Tesla aircraft would drain its batteries and overheat the motor within minutes.
Wave drag is primarily and effect in the *transonic* from about M0.8 to 1.1 or 1.2, and then basically disappears at speeds above that.
Wrong. Why don't you do some basic fact-checking yourself before wrongly accusing others?
This "new" technology sound as if they move from double precision back to single precision. Of course it needs less circuitry and power.
Yeah, Marvin is a fictional character, but it's believable to me that true artificial intelligences will get bored, distracted, make mistakes, etc., just like people, making them perhaps not much better than people at many of the moderately mindless tasks we'd like them to take on. So we'll have to limit them to make them good at what we want them to do... which may make them not so good at what we want them to do.
You would need to implement emotions. Deep learning is still completely void of emotions, and that makes it better at what it does than humans.
Are modern engines as efficient at Mach 1.5 as they are at Mach 0.9?
No. The engine doesn't notice the speed, the intake takes care of that. But to create thrust, the exhaust flow must be faster than the intake flow, and making the exhaust flow faster lowers the overall efficiency of the engine. This is why subsonic engines have a high bypass ratio while for supersonic engines bypass ratio must be kept low.
But there is a pocket of aviation where progress has been made in flight speed: Business jets! While the first generation flew more slowly than airliners (Lockheed JetStar, Lear Jet 25), the latest designs are quite a bit faster (Cessna Citation X, Gulfstream V) at up to Mach 0.935. Why? There is a peeing contest going on among their owners who is the fastest. A very small segment of mankind is licking their fingers at a new chance for showing off. A supersonic business jet would be a sure sell to this crowd, even if the operating cost per mile doubles.
Well, see it this way: This is a chance for the other 99.9% of mankind to lower the Gini coefficient a bit.
When Volkswagen experimented with 4-workday weeks 20 years ago, local plumbers and carpenters fell on hard times because everyone now used the extra day to fix things themselves, or even work on the side on that extra day. While the unions keep telling you that workers would relax during the extra time resulting from reduced work, in reality everyone tries to make a little extra on the side.
Also, having a job gives meaning to your life. Being told that you will be needed less is like telling you that you are a burden - nobody wants to hear that. That is also why today both parents work, even though they could enjoy the standard of living of a single-earner household of 50 years ago. But to keep up with the Joneses and to feel better for themselves both are now working, and the downside of less parenting seems to be generally accepted.
A budget is just a method of worrying before you spend money, as well as afterward.
