Between AI and shitcoin mining, these two “technology branches” already consume more power than all the green power added to the grid combined.

And your sources? I only did a cursory search, and according to the IEA data centers are responsible for somewhere in the range of 2-6% of electricity demand. Renewables are currently around 30% globally.

You can tell by the fact that jumping spiders are cute and recluse spiders are not.

so long as you are at least twice as large.

Which really isn’t that much of a challenge considering the largest jumping spiders are 2.5cm in length.

Hashcash isn’t “cryptocurrency”.

Battery and hydrogen-powered trains exist, they’re mainly used on less frequented lines because it would be more expensive to electrify them.

Am I the only one who thinks vacuums, washing machines, fridges and so on shouldn’t be connected to the internet?

It goes both ways, your employer can’t fire you at will either. But it goes further, usually you have a probation period, in Germany it’s up to 6 months during which you can leave any time, or be fired at any time. Beyond that there’s always the option to agree on a shorter notice period, but if you’re getting fired and you agree to a shorter period you won’t get unemployment compensation for that time.

I’ll add:

Radio waves always propagate at the speed of light, it’s just that the effective speed of light in copper and glass fibre is lower than that in air/vacuum.

This means that if you have long cables at some distance you’ll get a lower delay by using low earth orbit satellites like Starlink. Assuming a total distance via satellite of 1000km and the effective speed of light in glass fibre to be 2/3 c, cables over 667km will have a higher delay than the satellite.

The example is Amazon who have their own ARM CPUs for their datacenters. https://en.wikipedia.org/wiki/AWS_Graviton
