One of the problems with digging tunnels in a city is that it causes the ground to settle. Even with modern systems that have only little vibration and only little risk of caving in between the drill head and the tunnel wall.
If the ground drops even 10 cm on one side of a building, what do you think happens with it?

I want somewhere I can pick up my parcel at a time convenient to me. Luckily we have that here in the Netherlands. I can have the packet send to my supermarket and then I can go get it with my next shopping trip. No need to stay at home for a simple delivery.
Sadly Amazon doesn't work with it yet so I have to have that send to my work address.

Digging tunnels under cities is expensive. I won't say it's a bad plan, quite on the contrary, but it'll be expensive to get the tunnels in place.
I would love to see it work, motor vehicles in inner cities is a bad plan and this would make it possible to eliminate trucks from the inner city. After that making the roads bike and walk only is just a small step.

Never is almost always wrong.
For example, the wiki page on lenses. I think it is quite clear. It offers examples, formulas and the way of thinking when calculating a lens.
Do you feel that that is jargonated? Is the notation obscure?

Technical subjects usually have quite clear and correct wikipedia pages. As soon as politics enter it wikipedia is not reliable.

Add an RGB LED, add wireless power, sell em for 10K per buck and stick em on the wall as a screen.

Valve can have significant impact on that. It would just also significantly impact themselves.
Steam knows or can know what GPU you run it on, along with drivers etc. It could simply fall back to VGA without hardware acceleration for yet-to-be-released Nvidia GPUs.
That would significantly affect the Nvidia bottom line in the future. It would also place Valve in a bad spot.

Of course you can. You just need a $10M wirebonder to connect the IO to the computer.

Especially since at 10 bar the boiling point of water is 179C.

Higher frequencies are easier to form into directed beams dynamically with phased arrays. Not that I have any indication that Nokia has done this.

Absorption by water molecules really picks up above about 6 GHz. This limits the practical range for high frequency signals.

Just don't take the tapes to long term storage with an elevator with motors that erase all tapes before they get to storage.

High RPM drives are quite quickly being replaced by SSDs.

I downloaded a few keyboards and settled on Minuum. Default Samsung sucks, Swiftkey was way way better at typing but still took to much space. More than 50% of my screen in landscape mode. Minuum gives me the screen space to actually see what I am typing. It could do with better prediction though.

Traffic data is included in modern navigation systems. Last modern car I was in just asked me something in the lines of "Traffic congestion ahead. Reroute?".
