If we are playing the guessing game, almost all of them. Its not that expensive to build and run a closed loop water system. You cant just run plain tap water through cooling loops, it needs to be distilled or treated, or youll grow mold inside the loops and get clogs.

Provide your source for these data centres using open loop systems.

    Its nonsense.

    a) 16oz is 0.5 liters. To evaporate 0.5 litres from 20c to 101c you need 361 Wh of energy. An nvidia B300, top out at 1400W. In order for a single prompt to use 361Wh on a B300, the prompt needs to take 15 minutes to run. Thats clearly not happening.

    b) Even when water is used to cool GPUs, it isn't destroyed. Its heated, and then cooled down again. The water just moves heat around the system, it doesnt get destroyed

    Smart home stuff is dominated by Tuya, which is Chinese. Even a lot of the american branded stuff is Tuya rebranded. Phillips hue is Netherlands based, and from a quick look isn't tuya. IKEA is also not tuya. The rest, I would basically guarantee are all tuya based.

    Casual users don't need to setup vlans, because they simply don't care.

    There is no point hand-wringing about this, they don't care, they don't need our help for this.

    User process makes sense, but login shell is probably limited value. If your service gets pwn'd the attacker will spin up a reverse shell, and that isn't protected by the login shell. You ideally want to use selinux/apparmor to prevent execution, or containers to limit the available execution environment.

    I don't think AI changes that balance all that dramatically. Any business that won't hire juniors now, wouldn't have hired them before, and simply had the "Must have 20+ years experience in [flavour of the month] framework" in their job ads.

    And experience from past jobs hasn't really counted for anything beyond "They werent stupid enough to get fired", so paying for experience doesn't make sense either.

    All that said, regardless of who has the better crystal ball, its a shit time to be a compsci grad...
