    data centers and supercomputing facilities, which consume voracious amounts of electricity and water Memphis is on the Mississippi. Evaporating the volume of the Mississippi at Memphis with graphics cards would be a pretty impressive feat. kagis https://snoflo.org/flow/report/tennessee/ TENNESSEE FLOW REPORT August 22 2025 Streamflow levels across Tennessee are currently 92.0% of normal, with the Mississippi River At Memphis reporting the highest discharge in the state with 354000cfs 345,000 cubic feet of water per second is a pretty substantial amount of water. EDIT: Water has a heat of vaporization of 2.23 kJ/g. 345k ft³ water is 9.7×10⁹ cm³, so 9.7×10⁹g That's about 2.2×10¹⁰kJ to vaporize it (disregarding the specific heat of water, just the heat of vaporization). 1kJ ≈ 0.28 Wh. So 6,160,000,000 Wh to vaporize the water going through in a second. 3,600 seconds in an hour. So at a flow rate of 345k ft³ that'd sink about 22 trillion watts through vaporization alone. https://www.e-education.psu.edu/egee102/node/1925 In 2024, the world wide energy consumption was about 186,000 TWhs 8760 hours in a year. So global average power usage is about 21 TW. If we put the entire world's generated electricity towards heat to vaporize the Mississippi at Memphis, it'd still fall a bit short. EDIT2: I also inadvertently transposed two digits (should be 354,000 ft³/sec rather than 345,000 ft³/sec) in transcribing the initial flow rate, so it'd fall slightly shorter.

    There's no need for the government to prevent people from becoming wealthy. The only ways to become that wealthy all involve monopolies. But every single monopoly that has ever existed, has only managed to become a monopoly due to help from allies in government. AKA Regulatory Capture. When governments are large, and filled with bureaucrats that aren't answerable to the public, monopolies are far more likely to emerge, as those same bureaucrats enact more and more regulations that make entering the market more and more difficult for those of modest to little means.

    No need for good computers to train agents. They don't need to play crysis to train as hackers. Something on the level of a Pi (or more accurately of a 2010 laptop) is good enough.

    And a 24TB drive goes for 350, I don't see prices going up either

    That's a valid point! I've been searching for places to hangout for a while, sometimes called "campfires". Found a cool Discord with generous front-end folks (that's a broad spectrum!), on frontend.horse.
