In the long run that could become a massive strategic advantage for the US. A 2nd layer of resilience over undersea cables

A privately-held strategic advantage?

Plenty of US strategic advantages are privately held or otherwise very dependent on the private sector. It's fine because the company can't really leave the US.

It doesn't really matter who owns it as long as it can be bent towards national goals when it matters. American vehicle manufacturing was a strategic advantage during WWII because they swiftly pivoted to selling tanks to the government instead of cars to civilians.

It's already been bent towards missile defense https://wikipedia.org/wiki/Starlink#Military_capabilities

So that is "432 Mbit/s per laser, and 9000 lasers total". I don't know you guys but I find that statement much more relatable than "42 PB/day". Interestingly, they also say each laser "can sustain a 100Gbps connection per link" (although another part of the article even claims 200 Gbit/s). That means each laser is grossly underused on average, at 0.432% of its maximum capacity. Which makes sense since 100 Gbit/s is p…

Netflix uses 3-7GB an hour. The average person is spending 4-5hrs a day watching TV. I’d say most are above 100GB/month. But that’s me.

Do you have a source on the 4-5 hrs?

How do you spot a satellite? I've never seen one.

The Starlink ones look like Santa's sleigh https://i.imgur.com/4S0vbfY.gif

Nice image. The Starlink V2 are bigger though, so fewer per launch (~15 vs ~60).

Yep, but that data originates from the providers network and never leave the providers network, so they probably don't count it towards your usage the same way.

I don't think that breaks net neutrality either, which the FCC seems to be reimplementing

Offloading the risk on private players, reduces the amount of government investment required, and shields them from any criticism, should the project fail. Also, if it is that strategically important, the government can just buy SpaceX.

They probably wouldn't have to buy them, if there's a war on they probably have enough legal tools to just require SpaceX to sell them whatever capabilities they have.

At that level of strategic usefulness ownership stops mattering if shit hits the fan. It'll simply get commandeered.

Data might get counted multiple times as it takes many laser hops to reach its destination.

300+ minutes a day for TV + vMOD (streaming services). Since no one actually watches TV anymore, at least not through traditional TV, I summed them.

I think the average Instagram or TikTok user must be using more than 100GB/month. And if you count YouTube and Netflix, it's probably more than that.
