The EU is banning 8K TV's!!!

LED is hands down superior to CFL, no argument there, but CFL was not THAT bad, the better ones worked pretty well. There definitely was a tradeoff between cost, starting speed and lifespan. People like instant on, but striking a fluorescent lamp without first preheating the cathodes is very hard on them so instant start lamps fail a lot faster, they're really only intended for applications where they are started once per day. Put one in a bathroom or something and they will fail quickly. Amalgam lamps are better able to tolerate high temperatures so most enclosed globe style, super compact and high output CFLs used that rather than elemental mercury, but amalgam types take a lot longer to reach full brightness.

Limiting a kettle to 500W would be pointless as it's not the power that matter but the energy.  To boil a liter of water might require about 330KJ and it will make only a little difference if the kettle operated at 500W versus 2000W.  Actually, the 2000W kettle might consume a bit less energy as there would be less time for the kettle to lose energy through radiation or convection.

An 8K TV/monitor will tend to consume more power at a given size and brightness as it will have 4X as many transistors switching as a 4K TV/monitor does.  But, an 8K TV of, say, 25 inches diagonal will not likely consume as much power as a 4K TV that's 55 inches when operating at the same brightness.

Putting a limit on power consumption now when very few people have 8K will give the makers time to improve the technology.  Given the energy issues the world is facing right now with the insane war Russia is waging in Ukraine it is not unreasonable to impose restrictions to limit the blackouts and brownouts that are almost certain to be with us this winter.  During WWII rationing was a thing and although many hated it they sucked it up because they cared more about their neighbors than is common these days.  We have evolved into a bunch of whining toddlers stomping are feet and pouting!

It was only an example to illustrate a point I think. Also since when has something being pointless stopped a politician from trying to legislate it?

Politicians can promote anything they like, that's politics.  But the EU is a technocratic organisation.  Things are debated amongst industry professionals for years before even a draft piece of legislation would be written.  No doubt the 500W kettle limit will never happen.  If anything, the EU might mandate a 3kW kettle as standard, because it will likely be more efficient than a 2kW model.

There is no way in hell he would have let iOS7 go out in the state it was, or the notches in the displays of iphones and now macbooks.

Walter Isaacson, who wrote Steve Job's biography book, told about an episode at the hospital where Jobs was having his surgery, when Jobs did not like the oxygen mask he mentored the personnel how to improve the mask design.  8)

Nice story, but the people using it are not the ones with the say in changing it.
Besides, things that looked like improvements to him might compromise other parts of the design.
