Yep, you're right
I was just responding to parent's comment about fiber being best because nothing is faster than light :)

When copy says, "the X of the future will have Y," it's often laughable how wrong they get it
but in this case, remarkably true.
That's...not really a cogent argument.
Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).
Light in a fiber travels much more slowly than in vacuum
light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they're just a) not in free space and b) generally not optical frequency, so we don't call them light, but they are still governed by the same equations and limitations.
If you want to get signals from point A to point B fastest (lowest latency), you don't use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/
Finally, the reason fiber is so good is complicated, but has to do with the fact that "physics bandwidth" tends to care about fractional bandwidth ("delta frequency divided by frequency"), whereas "information bandwidth" cares about absolute bandwidth ("delta frequency"), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz
so a tiny fractional bandwidth is a huge absolute bandwidth.
80% of the USA lives within urban areas (source). Urban "fiberization" is absolutely within reach.
Agree that running fiber out to very remote areas is tricky, but even then it's probably not prohibitive for all but the most remote locations.
Yes, but you're not alone (my partner tends this way).
Don't forget Pinarello! Gorgeous and, last I checked, very well regarded. Just make sure your wallet is prepared
you can definitely drop $15k on a well-spec'd Pinarello Dogma.
The CW folks would presumably be sending QTH instead
I wonder if this graph captures that/if it would make an appreciable difference?
I just wish they made toddler clothes in my size.
Grass is ugly no matter the state it is in
I think bamboo can be pretty though 🤷
With a toddler and a baby, going to bed as close as we can to 8pm is one of the main reasons we're not sleep deprived (the other is that they're good sleepers).
So the irony is
I see what you did there...
People praise the female reproductive system as miraculous because it can make a baby in only 9 months. Like that's neat and all, but my reproductive system can make a baby in approximately 13 seconds, so I don't see what all the fuss is about.
