Missing features maybe. Like OpenMP, which is not there yet. LLVM and GCC feed off each other. Some competition is good.

Trinity was a 20kt bomb exactly like the one that obliterated Nagasaki. Hardly very small.

So, people in Texas who try to use the board of education to promote textbooks that have a negative stance on evolution? These people are from the left? I wasn't aware.

I have this theory that rich people like having to waitlist for luxury items. This is not so much for the items themselves (although they to provide a nice status symbol), but to experience what it is not to be rich and having to actually lust, expect and wait for something. If you want, to experience a kind of elusive desire for something they don't have. Most of the common goods they can have immediately, this makes this common goods, irrespective of actual price, worthless to some degree.

We relatively poor people experience that all the time even for somewhat mundane items like a telephone or a car. How lucky we are. Truly poor people experience that for essential goods like food, and that sucks.

In other word, it is not possession per se that create happiness, it is the desire, expectation and sense of achievement that corresponds to this possession that matters. If one is into possessing things of course.

The guy does what he wants. As long as his customers are OK with it, why do you care?

Honestly, these days a computer might last 10 years without being hopelessly outdated. 2 decades ago, there was no point in building a PC for it to last, it would be obsolete in 3 years. Now it a good time to buy quality components. Start with a reliable power supply, a great case, high-quality disks (they do exist) and so on. Use RAID if you can (at least a mirror) and do backups. Your data is more important than your hardware.

Apple is not for gaming, that's it.

Like most engineering problems, once a solution exists in prototype form, it looks like a solved problem to the marketer. In reality, there is a big distance between something that sort of works in ideal conditions and something that is really reliable under most conditions. Driving safely and efficiently is a difficult problem, at present requires expensive sensors and a lot of computing. It will get cheaper and easier and more reliable and will probably be useful. However I think we will still have a full set of manual controls in cars for decades to come.

Actually, computer vision, in terms of difficulty, is indistinguishable from strong AI. Look up the term "AI-complete".

Learning to fly a small airplane requires a lot of money and dedication. Only a tiny minority can do this at present.

What is the material, labor and recycling cost of doing so ? Lack of space is likely not the blocking issue with solar. Google probably has the answers.

Sunlight? What's that?

Science gets things wrong all the time. In the pursuit of the understanding of Nature, we only have a few reliable tools. One of them is modelling. Nature so far has resisted all attempts, and so all models are wrong at some level. However some are useful.

The general thinking is that we will never have a perfect understanding of Nature, and so Science will never be completely right and completely finished.

I think the GP's point was that if a watch is really expensive then a thief will not stop at cutting off your hand to get it.
