    Because Wayland is being written primarily by former X developers who have pushed X to its limits but have no choice but to start from the ground up to get modern features such as tear-free drawing.

    Strictly speaking that's not true, from the Wayland FAQ (emphasis mine):

    Why not extend the X server?

    Because for the first time we have a realistic chance of not having to do that. It's entirely possible to incorporate the buffer exchange and update models that Wayland is built on into X. However, we have an option here of pushing X out of the hotpath between clients and the hardware and making it a compatibility option.

    I guess the main reason Wayland doesn't take so much flak is that it's obvious the mission scope has vastly changed from the 1980s display server to the 2015 display server. And it's main deficiencies are most visible in the markets where it's barely present (desktop) or has been replaced wholesale (Android), while the init system seems like you're changing a winning team, honestly when was the last time init scripts was a deal breaker for anything? It has a much more "nice-to-have" feel to it or at least fixing corner cases most people never noticed.

Driving around with an AI that occasionally spectacularly fails would be like co-sitting a driver with a learner's permit, you're not less tense you're more tense because instead of the ordinary reaction time you only have the time from when you realize the AI won't handle it to react yourself. Not to mention the AI might surprisingly do something wrong creating a situation out of nothing with no warning. I'm with Google on this one, past a certain point either the car is driving or I am, you can't have two masters giving opposite directions. For example say that I intend to make a somewhat optimistic left turn, the car decides uh-oh the road's not clear so it slams the brakes just as I turn the wheel to cut ahead of the opposing traffic, we limp into the opposing lane and bang. Not to mention humans aren't very good at long intermissions, we'll start thinking about or doing other things instead of watching the road. They said they saw this the very first time they let non-project Googlers drive this extremely experimental vehicle, asking ordinary people to do it is pointless.

  3. Economic theory is sound, speculation isn't on Author Joris Luyendijk: Economics Is Not a Science (theguardian.com) · · Score: 1

    There's a massive bulk of economic theory that explains the applied math of running a business. Can you figure out if $1000 now is more or less than $1100 five years from now given an inflation rate of 2%? The relations between price, quantity, marginal costs and profit are also quite sound. The thing is though, all this information is allegedly available and equal for all, so if everyone agreed to the same model there'd be no profit to be made. Sure, the future would be unknown but it would be like a lottery ticket being scratched, everybody knows at all times the exact value of all the possible outcomes so everybody prices in the same expected value of the future. If you can find a way to make arbitrage, you've found a flaw in the way the market works. For example if you discovered you could make money selling products in one currency and buying them in another, or transporting goods from one market to sell in another for more than the transport and insurance costs.

    Speculation is all about betting on these flaws, but sometimes the market has priced in risks you haven't imagined. Or there are forces that only become dominant at a certain size. In this particular case it was more like you create a theory of chemistry and when the market goes to an extreme you have nuclear fusion instead. That doesn't make chemistry wrong, but at certain times it's irrelevant and you can't rely on it to always produce correct answers. Oh and just to put a nail in that coffin, no scientific theory is proven to be universally valid since there's still the future and it hasn't happened yet. There's no absolute guarantee gravity will work the same five minutes from now, if it suddenly starts behaving different it just will. In that case reality will be right and the formula wrong, no matter how correct and comprehensive it might have looked.

If you need to get a charge at work or some other charger every day, you're pushing the limits of good sense. My guess is that there's two kinds of people charging, those who just use it as free electricity instead of plugging in at home and those who could really use it because they have been/will be driving far and needs the charge.

It's probably impossible to design a system that couldn't be manipulated once you start disenfranchising people. Who gets to define the relevant "knowledge"? How do we measure " intelligence"?
