The only thing dead here is the mass between your ears.

The saddest thing about morons is that that they think their moronic nature is a matter of pride, and not shame.

I think it was fairly clear what was going on, the neural networks latch on to conditions that are necessary but not sufficient because they found common characteristics of real images but never got any negative feedback. Like in the peacock photo the colors and pattern are similar, but clearly not in the shape of a bird but if it's never seen any non-bird peacock colored items how's the algorithm supposed to know? At any rate, it seems like the neural network is excessively focusing on one thing, maybe it would perform better if you divided up the work so one factor didn't become dominant. For example you send outlines to one network, textures to a second network and colors to a third network then using a fourth network to try learning which of the other three to listen to. After all, the brain has very clear centers too, it's not just one big chunk of goo.

I never understood what that Gandhi quote is so popular, sure that's what a victory looks like out the rear view mirror but most defeats start just the same.

If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.

How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.

Weight vs. reusable life will become a design decision in rocket design.

g++ supports it with __restrict__. And if you're writing high performance code but not having support for the features of modern compilers, you're an idiot. In appropriate situations, the performance difference for using restrict or not is huge. Array-heavy tasks like image processing often get a 2-fold or more benefit with using restrict. There's very few places in the coding word where a single keyword can raise your performance that much.

And examples of these which could plausibly be on Titan are....?

There's not much in nature that's that light.

So you think massive yachts, ridiculous-priced art/jewelry purchases, palatial estates, gold-plated toilets and the like are a better use of money?

Trust me, I'd have a LOT more fun with a giant rocket than I would with a gold toilet.

I'll begin by stating that I I don't support such a mission, as I prefer robotic exploration. But this proposal isn't as extreme as it may sound - it's probably a heck of a lot easier than landing on a planet and taking off. It's only 640 m/s from earth escape to Venus (3/5ths that of Mars). Transit time is less and launch windows a lot more frequent. Venus offers very easy aerocapture. You don't have to deal with the randomness of the surface - your "landing" is a lot more forgiving. Your habitat is probably simpler, not having to deal with a surface (although there's a few potential complications that need to be studied, such as storms, and I don know the radiation level at the desired altitude). Keeping it aloft is easy - even normal earth air is a lifting gas on Venus. Solar energy arriving at Venus is double that of Earth. Nearly earth's gravity eliminates a lot of the uncertanties about skeletal and muscular wasting.

One of the neat things is that a person could potentially step outside without any sort of special suit, just an oxygen mask. It's a "maybe", though, as there's a few complicating factors. It's 37C (100F) at the same sort of heights that it's about 600mb; for US analogies, it's Phoenix temperatures at Mount Whitney air pressures (lower or higher for both, depending on your exact altitude - you can choose). So it's not a perfect match - but probably tolerable. But there's two potential complicating gases: SO2/sulfuric acid and carbon monoxide. Breathing them is right out, but even long-term (hours at a time) skin exposure might be problematic at the given concentrations; it's not certain whether at these altitudes they'd be prohibitive. They would however make eye protection a must at the very least, the eyes are more sensitive to both CO and SO2 than the skin.

Manned or not, the main advantage of a Venus blimp would be the lower altitude it would provide to scientific equipment versus satellites. So you'll get a lot more information on the atmosphere, which could help answer questions about Venus's evolution (and how other worlds in other systems might be). You'll get higher resolution radar imaging of the surface. You simplify to some extent sample return missions from the surface, as each sample collection doesn't have to be a self contained return mission. Etc.

One thing on Venus I'd love to see studied more is the super-reflective radar surfaces. It's now believed to be due to a "galena snow", snow made of shiny, electrically conductive lead sulfide. I'd really love to know more about the surface minerology of Venus in general.

You give the elites credit for way, way too much foresight, organization and discipline.

I'm not talking about ideals, or tourism, or saving the world, or finding anything "up there", or anything of that nature (did you even read what I wrote?). I'm talking about the sheer awesomeness of, at your whim, shooting up a 1500 tonne rocket into orbit then landing it on an automated oceanic platform. It's like playing Kerbal with a real-life 70-meter tall rocket. Why don't more billionaires do stuff like that if only just for the fun of it?

But clearly you have an axe to grind against something for some reason, so I'll let you get back to that wheel.

Why don't more billionaires do stuff like this?

I'm not saying do it "for the benefit of humanity", or even "for a profit". Just simply.... if you have billions of dollars, and you want to spend it on something, what can you possibly spend it on that wins in a sheer awesomeness category as "shooting a gigantic rocket up into orbit and then landing it on a robot boat in the middle of the ocean"? That's like a freaking video game, played with 1500 tonnes of aluminum and highly combustible fuel.
