    Horses are expensive to maintain, and have a rough daily limit of about 30 miles. In comparison, a human walking at 3 mph can go the same distance in only 10 hours.

    That's not comparable. The horse could do that forever (for example, see this US cavalry manual which stipulates cavalry can go 35 miles a day, six days a week indefinitely - page 152) while the person would not be able to maintain that sort of pace for more than a few hours to a day unless they were in really good shape.

    In comparison, typical indefinite marching rates for an army were about 10 miles a day (both for roman legionaires and US soldiers).

    It's very comparable. A human can keep up a 3mph walk forever as well. A 3mph pace is not hard for a human at all and without
    a pack 30 miles a day would not be an issue for a human. 35 miles per day, six days a week indefinitely would not be a problem for
    the average person either. I don't think a march with camp setup, etc... is comparable to what the original poster was talking about.
    I think you underestimate what a human is capable of. When I was in college we went on a hike to the bottom of the grand canyon
    for a week. None of us were in great shape, did any training, or probably near as fit as a peasant who worked all day in the field
    every day yet we averaged about 20-25 miles a day for a week with heavy packs on rough terrain and making camp each night.
    We obviously could have done alot more with a light pack. And again, we were not in shape, didn't train, and most had never even
    been backpacking before. For endurance running a human is every bit as good as a single horse. The pony express used multiple
    horses because horses are faster over short distances but over multiple days a human is actually faster. A good runner can do alot
    more than 35 miles per day. This guy averaged over 50 miles a day for 40 days:

    If current routing tables can't scale then maybe a different type of routing table or a different solution entirely is needed.
    For instance if every router was location aware and knew it's geographic location and the geographic location of the place it was

    I agree that doing it yourself is pointless but not hopeless. The internet has lost it's goal
    of routing around failures. We should try to move to a decentralized internet. The simplest
    and easiest way to do this is with sharing wifi routers. Most people in a city can see
    multiple wifi routers. If the routers all talked to each other and shared bandwidth then you
    have dozens of paths to the internet. This could even be expanded to cars. While
    driving on the highway there is typically a string of cars stretching from your car all the way
    back to your house. If each of these cars had a router in it you could just hop from car to
    car all the way back to your house or all the way across the nation on any major highway.
    We need to work on decentralized grid routers to completely remove the internet from any
    one entity's control.

    Risk can be minimized if you're willing to take sacrifices instead (which could be argued is a form of risk).
    Many people I know (including myself) started their own business by working part-time at a minimum wage
    job to keep from starving. This is obviously harder if you have a mortgage, kids, etc... but many times even
    with children if you lower your standard of living a little and find a flexible part-time job then you can
    eliminate most of the risk in exchange for some temporary sacrifices and if it doesn't work out the only
    thing you are out is a little bit of time. There are other ways as well for instance find 10 friends who are willing
    to give you a stipend so you don't have to work the first few months, are able to help cover your startup costs,
    etc. A sole provider quiting their job cold-turkey with a mortgage, car payment, etc.. is taking on a huge
    amount of risk but if you move into a small apartment, pay off you car, and distribute the risk among several
    friends then the risk becomes much more managable. When I started my business I used a combination of
    investment from friends, part-time jobs, volunteer labor, and even friends pitching in to give me a small paycheck
    which means that no one person had a significant amount of risk and because we were successful everyone
    eventually ended up getting their free labor and investments paid back but if we wouldn't have been successful
    noone was ever really out more than they could lose.

    I disagree with this part. Yes, your income is more stable week to week but so what? You shouldn't
    be living paycheck to paycheck anyways. Someone who is self employed actually has more stable
    compensation in alot of cases especially if they have multiple clients as they can't show up to work

    And I know multiple people who are employed yet decline employer benefits and keep their own
