In theory yes, but it's just not realistic for the whole world. In the western world, yes, we can isolate us if we want. It's just not that easy everywhere.
I use PiHole and installed Wireguard on my RaspPi. Works really well, and I can bring the PiHole-functionality everywhere while easily toggle it on and off.
They don't need to take your phone with them. They literally can just scan the code, because it sends all the info to their screen, that they were gonna look up anyway.
No way the government implemented an app for this use case. That's extremely inefficient.
I thought you actually tried, that they took your phone?
And hopefully they'll do that. The shit you can find on Twitter is alot more sick than TikTok, and you can be sure Elon would make it the same shitshow.
The silicon batteries can store alot more power in the same size and weight.
That means you can put alot more power into your existing size of hardware.
It's also extremely beneficial for electric cars, which can either lower the weight on the car or put more juice in it. Both increasing the range.
For your point about replaceable batteries, it's true. If we can replace batteries, the hardware will not be lost. But everything comes down to how often we need to replace them. How fast does these batteries really degrade in real world use? It can leave us with even worse ecological challenges and might be very expensive. We need a strong reuse culture for this to not be a new catastrophic environmental case.
The real deal is this though:
A third option is Solid State Batteries and is still the best solution for the future, but it's not fully ready for commercial use yet. They do not seem to have any of the downsides from both lithium and silicon. But again, it's not ready.
Yes, in phones we can limit the damage by using slow chargers.
But when it gets hot, it's also a lot worse than with lithium. Not only do they degrade permanently, but they also loose more power while in the given operation.
Meaning while hot, your battery might burn 10% but only use 5% worth of power.
Some phones also gets hot when gaming or shooting pics or videos because of the CPU. If the thermals are manged poorly, it can permanently damage the battery as well, which we do not see in lithium.
Yeah, it's not like they don't have competitors, but this makes it sound like they're alone on the mountain.
