IMO the law is intended to reduce consumer electronic waste, making batteries that anyone from kids to grandparents can easily replace themselves. Currently the steam deck battery isn't all that difficult to replace for the tech savvy "brave" folks who happily open up their devices and see the internals, but for most people that's not good enough. I would never expect my 68 year old mother to replace it herself. IMO the aim is to make batteries replaceable like the PS5 SSD expansion capacity is. Just need a screwdriver and a few minutes, without every feeling like you might break something. Needing anything more than that and most people won't do it out of fear they'll break their device.
But only time will tell what actually happens.
OMG That's wage left!!! You should be ashamed! The boss could make more money if you work more like a robot and less like a human being! Heck, if you were an actual robot they wouldn't have to pay you at all! Think of how much the stock price could go up then! Robots don't complain about living wages, require training or form unions, and they don't worry about climate change and ecological collapse! The perfect worker.
