    I think fragmentation is the biggest cause of fake news. When there were only a few viable news sources, they had to cater to everyone so stores were less biases and fact checking more rigorous. But if you can be a viable news source that only targets to a fraction of people who are predisposed to be less critical of you, you leave the door wide open to fake stories because the penalty for a fake story is nearly non-existent (you will be likely forgiven by your audience).

    Ask a paleoanthropologist and they will tell you that you are full of shit about the lifespan of early humans.

    One issue that may be of interest is fossil records show many examples of humans and neaderthals and analysis shows that many were likely to have died at an older age due the observation of common age related dental issues (such as ground-down and missing teeth) and arthritis. Unfortunately fossil records are rare so it isn't possible to determine the average age related issues, and even if there were many more fossil records, they cannot determine cancers or cardiovascular issues from fossil remains.

    As mentioned by other posters, refined sugar and other refined carbs have been identified as a likely candidate (potentially more significant than saturated fats from meat) for many of these diseases, but the jury is current out on that topic.

    The reason prehistoric man was attributed with short life-expectancy was because of high infant mortality and childhood deaths (disease and other mortality risks). If we factor those things out, prehistoric man is estimated to have lifetimes similar to those in the 16th century humans. These extrapolations were done by a few decades ago in scientific studies of isolated hunter-gatherer societies in Africa and South America before there was significant contact between these isolated groups and modern society (unfortunately that they are difficult if not impossible to repeat now because of widespread cultural contamination).

    You can take these with a few grains of salt, but it tracks with estimates done over historical times (where they have better information) that factoring out infant/child mortality effects, the lifespan of humans has been pretty constant until the industrial revolution when people started living a bit longer. Post-childhood causes of deaths that limit life-expectancy have changed greatly over time. In the hunter-gatherer society external injuries dominated the deaths, in the agricultural society the prevalence of infectious diseases dominated, it wasn't until the industrial revolution that cardiovascular diseases dominated, but as we move to a "high-tech" society cancers now dominate over cardio-vascular disease.

    Since our diets have changed since the earlier part of the industrial revolution, I don't think we are eating *less* meat than we were before during the industrial revolution (where we were collectively much poor-er and couldn't afford much meat) so I'm not so sure it is conclusive that meat is the cause of all this cardio-vascular disease during the industrial revolution, and I'm not sure it's a cause of the current cancer epidemic either. Personally, I suspect generally higher calorie diets and less exercise for cardio-vascular disease prevalence and prior-generational under-reporting combined with increased industrial pollution for the modern cancer prevalence. I have no evidence to support this, but I suspect many will agree with that assessment.

    Maybe when it is relativistically heavy enough it can no longer accelerate?

    Relativity doesn't stop you gaining momentum. You can still accelerate, your speed will asymptotically tend to c, and your mass will increase, but you never stop. Besides, it's relativity so it has to be realtive to something.

    FWIW, it think it's generally better to think of your mass not actually increasing, but simply your momentum. The "fiction" of the mass increase is only to preserve the newtonian idea of F=ma, but if you instead think of this law as F=dp/dt, you never have to wonder where that extra mass came from (as a bonus this also works in the 4-vector space that makes it easier to compute relativistic relationships)...

    That's mostly because it's easier to tune a carb than to rewrite the EFI software for a custom engine config, especially if you are only running it full throttle on a drag strip.

    Um, California doesnt really get water from outside the state to any great degree. It's the California part of the Rockies that provides the snow pack that feeds the water needs of Southern California and the Valley. The rest of the state makes due with its own reservoirs.

    I think you need a geography lesson. As far as the maps I'm aware of, no part of the Rockies where the Colorado river originates are within the borders of California.

    AFAIK, In Northern California most of the water comes from Sierra Nevada range. In the central valley, about 1/2 comes from the Sierra Nevada and another 1/2 from underground aquifers. Unfortunately for Southern California, most of their water comes from the Colorado River.

    I used to live in CO, and the issues surrounding the Colorado River Pact of 1922 continues to be a *major* political issue in Colorado. Over the last 50 years, California has been using more that its allocated portion of water (which is allowed by the pact when there is a surplus), but California has also been using its influence in congress to block other states from creating reservoirs to capture surplus for drought years. Sometimes in drought years can get pretty acrimonious, and agriculture concerns in Colorado call out California for conspiring to steal water by blocking reservoir projects.

    If CA were to secede, I'm sure northern CA would be fine, but I suspect southern CA would need to get major concessions to get the "bonus" water they have been relying on from the Colorado river basin.

  20. I'm wondering then why we have West Virginia...

    The state of West Virginia (aka Kanawha), was formed when Virginia seceded from the union prior to the Civil war. During that time there were 2 legislatures that claimed to represent all of Virginia. The legislature that didn't support succession voted to approve to split the state and this was approved by the US Congress compliant with Article 4 of the constitution.

    In the case of California, I don't think the legislators that represent the central counties in the CA state legislature, nor do I think the US Congress would approve splitting the state. This comes up in Texas all the time, and the same thing is likely the limiting factor. In any case, it seems totally unlikely that the Congressional representatives of small states would ever agree to splitting a large state to help it gain more representatives in the Senate.

    At some point if you socialize all loss potential, you get too big to fail, and potentially non-optimal use of resources (e.g., 100' s of companies doing something in an area where the market can only support a few), so there is definitely a cross over point somewhere. I don't think anyone knows where that is, but it isn't at the zero risk point.

    You might argue that at any specific point in time, the economy might benefit on the margin for a few more startups, but as we can see from history the current system continually business cycles from a few startups where you get fewer winners (dot-com) that stimulates a time of startup oversaturation and lots of failures and retrenching (e.g., dot-bust). Thus we have crossed whatever that optimal point is many, many times and overshot both ways. Don't really see how "stimulating" the creation of even more startups is ever a good idea economically in the long run as it will probably only increase this (in frequency or magnitude). It might "feel" like that is a good thing if you are some hot-shot young engineer that hasn't put down any roots yet, but other sectors of the economy (and real lives) can get disrupted by these inevitable cycles.

    There might be some other social benefits of UBI, but if we could *DISCOURAGE* the use of UBI to support more startups, then I would be more amenable to it.

    I think you misunderstand supply. There isn't a supply of billions of CEOs that will work for a $1. There is a supply of a several thousand (or so), the others are more-or-less "unqualified" (not that they can't do a similar job, but they are unhireable because the boards of directors don't want to get in trouble for hiring outside the expected hiring pool). Similarly there isn't a supply of billions of IT folks, and similarly hiring managers generaly don't want to get in trouble by going outside the "standard" hiring pool. This used to be called nobody got fired for buying IBM (but that probably goes the other way these days)...

    The problem is that there is probably no good way to evaluate employees (including CEOs) before hiring, so most people simply pay the going rate, and hope for the best. The going rate is set by the limited supply and how desperate companies are (e.g., the demand side). The outsourcing comes in when the demand at the lower price point exceeds the supply and gets supplanted by a demand at a lower price point (and potentially larger quality variance) which matches the supply.

    This used to be called the resistor tolerance dilemma. 1% tolerance resistors are much more expensive than 20% tolerance resistors. You might think if you bought enough 20% resistors you could cherry pick the ones that had lower tolerance, but in reality, the vendor pre-sorted for this, so if you bought the cheaper resistors you could almost guarantee they were crap. However, it was reasoned that by sophisticated design choices you could theoretically reduce the problem of high variance resistors so people started doing that. So you could solve your circuit design problem with a simpler scheme, but pay more for resistors, or have a more complicated circuit (with more things to manage that could go wrong) but get it done with cheaper resistors.

    As expected, managers in 2nd rate companies didn't grasp this inherent tradeoff and wanted both cheaper resistors and the simpler circuits designed by novice designers. They bought loads of cheap resistors and put them in these simple circuits as a cost cutting move expecting the distribution of resistors to have normal statistical characteristics. Lo-and-behold they would eventually get a batch of resistors that were all low by 15% resulting in a 100% escape rate from their production line.
