Proof of stake gets around the electricity usage. Of the chains that are still big it's really only bitcoin and it's derivatives that still use a lot of energy.
I think the kinks have been worked out. Samsung is on it's fifth generation of foldables already and Motorola has made multiple as well that haven't been released in the states. No idea about the custom ROMs though.
Be warned though, some x265 stuff out there, particularly at 1080p and lower, is a reencode of a x264 source file. So lower filesize, but also slightly lower quality. Scene regulations say only higher resolutions should be x265.
This used to be the norm, not a weird thing that noone has thought of before. If you do this your kernel will be a lot smaller, boot faster, and be a bit more secure. Once you're booted it won't make any meaningful speed difference though.
It really isn't. We know it's possible, we roughly know how to build one, it's only our material science that isn't there yet. But there are promising leads in that direction and with the right investments that problem looks solvable.

With FTL our current science is saying that it's probably impossible and will never happen. We might be wrong about that, but if we are it's not going to be cracked anytime soon.
My i3 has an OBD-II port, and it's not the only EV that has one. Bimmercode can change A LOT of vehicle settings through the port, and software like ABRP can use it to read out the battery level and route you to the next charger when needed.
