What does right or wrong mean? Is F=ma wrong? It's a lot simpler than relativity. Is principle of least action more or less simple than Newtonian mechanics? I think it's much simpler, but requires a year of higher math before you can do anything practical with it. I'm currently rooting for a CA interpretation which is about as simple as one can get, but so far no one has figured it out.
So you are one of those judgemental people who check out peoples history and downvote it when someone says something you disagree with rather on the quality of argument while failing to provide a counter argument.
When I took physics in college, I don't think 'nature of reality' was ever mentioned. It was all about outer products, Hamiltonians, PDE and residue which I found more interesting than the 'nature of reality'. I suppose this is why I sucked at being a physicist (my first major and short lived career). Clifford algebra was really interesting too, but I did not go that far. The only popsci physics book that I read was by Bohm. I started a few others but only made it as far as the first paragraph.
The mass crushes beneath it everything that is different, everything that is excellent, individual, qualified and select. Anybody who is not like everybody, who does not think like everybody, runs the risk of being eliminated.
How do you define "live better"? I tell people how to live better all of the time, but almost everyone ignore me. I don't care, it's not my responsibility to make sure they're living better.
Eg., get rid of television and read more history books.
Completely application dependent. What if your requirements are to operate 6 months on a single AA battery and the whole application is to shift out a 16byte sequence? There are about 20-50x more systems with requirements like this in the world than those that would require an atmel or arm chip. I worked on a system once that had such requirements because it was cheaper than a couple of TTL parts. This was a tiny subsystem on a larger computer board with real processors and RAM.
seen almost exactly zero evidence that this "trend" is real.
Are you looking at programming jobs or electrical engineering embedded development jobs? This is kinda the thing that an EE does almost as an afterthought.
em6882. Is there even a C compiler for that chip? There are many low cost chips like that in the world., Probably an order of magnitude more than x86 or arm combined.
Most of the world is small and trivial applications. I suspect this is not due to speed or size but more that many of the processors and (sub)systems are not complex enough to support a C environment. I do mostly EE related work and not much CS and have worked with CPUs that could not address more than a few bytes of memory. C is not a option in these cases. Something like this.
There are probably hundreds of different CPU's out there. Many for which specs have never been published. Everyone here has a PC class mentality, but in the real world, there are dozens of very tiny and primitive processors doing simple tasks that you never see. Decoding a front panel to a tv for instance. It may be less expensive to create your own proprietary cpu and have three million made at $0.04 each than to add the circuitry necessary for the main processor in your tv to handle it. Nobody is going to bother writing an optimizing C compiler for a processor that has six instructions and 16 bytes of memory. I've worked on many similar systems that would not most of the C language.
Modern cpu does not necessarily mean big complex processors. In embedded sometimes very small processors with simple instruction sets are used to save power and money. Sometimes a simple analog circuit can be done simpler in digital, but you may not need more than 6 bytes of ram or any more instructions than or, not, shl, mul. If that is the extent of what your cpu does, why would anyone bother writing an optimizing compiler for it?

The Smartest Book About Our Digital Age Was Published in 1929
Art is both illogical and irrational.
What is truth? Neither Google nor wikipedia have the answer.
Eg., get rid of television and read more history books.
How we get there
Eliminate all the irrational people would be a good start, no?
How do you get 50% more comfortable? If you are missing something in your life, then obviously you are not comfortable..
It is irrational to waste protein. It's even irrational to keep people around when a machine could do the job more efficiently.
And remember 15cents spread out over 30 million widgets is $5million.
even in the embedded space.

What would you do if your processor did not have a C compiler?
There are many MCUs that do not have a C compiler.

The 65xx chips are now implemented in FPGAs...and they still need programming. I'm serious too.

I never had trouble accessing registers using C
Odds are you do not know all of the registers on your chip.
And you thought you were joking.

In 2008, there were some 30 embedded microprocessors per person in developed countries (PDF). Most of those don't have plenty of memory. There is a whole entire world out there that you are likely unaware of.
I think most case statements switch from else-it to jump tables past about 5-6 cases.

could we get more anecdotal evidence?
I quintupled my starting salary through job shopping.
Who needs. or even wants, job security when you can retire before having to worry about age discrimination?
