    It’s quite relevant if you consider that coal mining is concentrated to a much smaller area really. Besides the destroyed habitat, the pollution, the dangers of sinkholes and the cost of renaturation you also have to contend with rain and ground water constantly filling in the mining pits.

    Don’t know about the UK but in West Germany’s Rhein-Ruhr area, a former coal mining hotspot, the energy used to operate the pumps that keep the water out will eventually be greater than the energy gained from burning all the coal. Can’t find a source on the quick but I think it might have happened already. Of course it’s not a simple subtraction as all that energy was used to generate more infrastructure and capital that can now pay for the pumps. According to this German source their operation costs around 300 million euros yearly which gives you a rough idea of just how expensive that is.









  • The wheel (for transportation) is really a concomitant of stable roads existing. Really wheels only work on flat, paved surfaces. The “invention” of the wheel isn’t the stroke of genius that pop culture likes to portray it as. It’s just something that follows from having the right environment. The Romans for instance built and maintained widespread road networks throughout Europe to quickly move troops to the front lines. It turns out that those roads also were a tremendous boon for traders and travellers using carts.

    Comic’s still funny though.



  • Too many games I’ve seen conflate being evil with being a jerk. Few games let you play the ‘long game’ where you are specifically nice and cooperative to deceive and manipulate. I think this partly due to decisions being made modular and point to point. Your overall morality then is calculated as some form of average of all the decisions you made. Mass effect series comes to mind.

    But if you want to play as a scheming villain the opposite should be the case: you set your primary long term goal (eg taking over a country or institution) and then your actions are chosen in the vein of that goal. And those actions might in isolation actually be seen as beneficial or benign. But you ultimately do them to gain trust or deceive.






  • Wow, this one actually had me intrigued. So much that I read the whole text below (which is also well written and deserves attention):

    The Cotton Looms get all the press in the early industrial revolution, but the Threshing Machine really might be the biggest jump in productive capacity in the history of the world. It cut out so much manual labor (people used to have to bash flails against the grain for hours and hours to separate the seeds) that there were riots all over because it caused so much unemployment and social upheaval. The famous Luddites, who people think of as being opposed to all technology, were mostly mad about automated cotton looms, and their consequences on society. They even went so far as destroying the looms (and other similar movements destroyed threshing machines). They weren’t just backwards thinking technology haters though, but rational people who noticed that there was something deeply wrong with how society was organized that a machine which improved efficiency so much was causing poverty and even starvation among the very workers who it should have benefited. It wasn’t the Luddites who were irrational, but the structure of society itself. After all it should be the people doing back breaking work who are most happy about a machine replacing them, but because all efficiency gains go to the owners, those people are simply out of a job. We’ve seen this time and time again under capitalism, and is even going on right now with AI.

    The dragon is based on Adam Smith, who noticed these kind of improvements in production were the key to increasing the wealth of a given society, and that reorganization of society from feudal lords, who largely spent their money on luxuries, to industrial capitalists, who spent a lot of their money on “research and development”, i.e. improving the efficiency of their factories, was causing economic growth and ever increasing wealth. In order to modernize, societies essentially had to get rid of the feudal lords put all of their money into the hands of capitalists as much as possible, to kick start this kind of economic growth.

    Without the comic I might never have bothered to read the text though. In that sense it’s very well made.
