As well as BTRFS and ReFS

Raid doesnt even protect against bit rot either. It doesn't matter how many disks you write to even in a raid one array you are still vulnerable. Unless you have a high end raid card that does block level checksuming your raid array will not go back and verify previously written to data is still correct. If it does have checksuming it still isn't smart enough to know which drive is the is correct and will lock the array in the best case.

You can kinda cheat and get the refresh rate down to 300ms with partial refresh but that's still one hundred times slower than a 30hz conventional display.

That's not how light/laser and prisms work. Prisms only separate out the frequencies that are contained within the light/laser. imagine the light is a sandwich and each frequency is a peice of the sandwich. If you take apart the sandwich you still have the same bread, meat and cheese just not stacked together. That's what the prism is basically doing.

LED bulbs for refrigerators and freezers are pretty easy to design since the lower temperatures will let the LEDs run more efficiently. Oven lamps might never get LEDs because normal solder starts to melt around 350F and will soften around 200F so unless they start making the bulbs with exotic and expensive solder we will never see LEDs in the oven.

because studio equipment uses 3.5mm or other standard jacks (XLR for microphones for example) as they cause the lowest interference.

Digital signaling is not susceptible to interference like analog signaling. Comparing three analog connectors to a digital signal is a false comparison. With a digital signal unless the interference is large enough to sway the voltage to the wrong side of the threshold it doesn't matter as it will still register a one or a zero. Analog signaling on the other hand is very susceptible to interference unless you use balanced connections which uses wave interference to remove the added noise.
