  • it’s mostly material cost, it’s described in more detail in the paper. it has nothing to do with economies of scale because we’re already installing massive amounts of cables today. there is a connection to the grid level (high-power lines are cheaper than low-powered ones) though.

    Still, I bet my favorite hat that once you consider the externalities and conversion losses the transmission lines are a clear winner. The electrical grid really only causes fires when its neglected, whereas gas infrastructure leaks constantly.

    nah electrical lines have significant losses. iirc from memory, 500 miles transmission over cables, you lose like 30% of your energy. gas leaks but not that much.



  • Monetizing everything is inherent in capitalism, though

    nah. there’s “limited capitalism” where only parts of society are monetized, like heavy industries. it’s neoliberalism that monetizes everything. this means that if you want childcare, you pay for it. in earlier decades/centuries, that was done by the wife / community.












  • an image, technically, is an array of pixels. specifically a 2-dimensional array. this means, it’s just a long list of lists of pixels. so if you have a 1920x1080 image, it’s just a list of 1080 lists of 1920 pixels each.

    each pixel, again, is a tuple (i.e. a list with fixed length) of numbers which specify the brightness of red / green / blue lamp. so if you want to display a yellow pixel, the data would be (1.0, 1.0, 0.0) which turns red and green on and blue off.

    so if you have a 1920x1080 image, technically you have 1920*1080*3 ≈ 6 million numbers. each number takes 32-bit, you can read it here



  • no, nice take though

    so you’re right that text, audio and video are important data types. if you look at peripheral devices of computers, you can find: keyboard, printers, microphone, speakers, camera, screen. they put text / audio / video data in / out of the computer. so there’s that

    however, internally, databases are incredibly important. basically everything inside the computer is organized in databases if it’s not some media that’s displayed to the user directly. therefore, a lot of files are database files (sqlite3 files mostly). they’re tabular data and you can watch them with sqlite3 command line program.
