I think it's likely a bad idea at this point to bet against Elon - he seems to make more good decisions than bad decisions, and is able to attract and keep the talent that is enabling his companies to snowball exponentially towards reaching the abundance of the universe. My deepest hope currently is that the riches of the universe now on the horizon of being relatively easily accessible, in a systematic and efficient…

Past performance is a piss poor indicator of future performance. You can’t deny (I don’t think) that the things he’s done are amazing. He’s in the zone where he’s smelt too many of his farts though, and believes he can do no wrong, which is historically a very bad place to be. I hope, for all of the awesome things he’s said he’d like to do, that they don’t come agutsa due to that

Really?

It's my understanding Elon isn't popular anymore (I could care less), but this point does not help whatever it is you're trying to say. I deal a lot with statistics and making predictions from past performance, and you most definitely can determine future performance with a high amount of accuracy. This shouldn't really need said.

You are probably right about him smelling too many of his farts, but you really hurt your main thesis right off the bat with that first claim.

This is HN. Everyone here is more intelligent, capable and aware than people who are industry professionals in their specific field.

Apologies. Will refrain from that in the future.

But with lasers, it makes sense to route your packets via space. For example traffic to a different continent would be faster (and cheaper) through space. Furthermore, I assume lasers have more capacity than gateways, so they could increase capacity of one satellite by bundling with more gateways.

Unfortunately, the routing to make this feasible doesn’t exist yet. Users need a single IP address from a range that’s homed at a single PoP. Starlink doesn’t support user-user connections through the mesh, you need to go all the way out to your PoP, then over to the other users PoP, then back through Starlink to that user.

Are you talking about peer-to-peer connections between two Starlink users, like if they were both in the same satellite's range but separated by a really tall mountain between, etc.?

What kind of worms?

All countries have strict regulations on radio waves, whether that's sending or receiving. The UK for example requires a license for base stations that stipulates things like geographical boundaries, etc. You can't freely blast radio waves into a country without falling subject to its varying regulations, but the regulations for "pre Starlink" satellite broadband/phones/etc are fairly well established.

Does this count for radio waves beamed in from space (like GPS)?

Who has 4-5 hrs a day to watch television? ..or am I completely out of touch?

According to historical Nielsen data[1] from 1991 to 2009: most Americans. Even back to 1950, for per household data, it was above 4 hours. [1] https://www.nielsen.com/insights/2009/average-tv-viewing-for...

2022 data from the BLS: https://www.bls.gov/news.release/atus.t11A.htm

Men spent 3 hours a day watching TV, and women 2.5 hours. But TV time is lower (around 2 hrs/day) from ages 20-44, then increases again after 45 and peaks at 75 years old at nearly 5 hours a day.

Households without kids watch more TV, which surprised me.

SpaceX, the topic of this thread, was wholly started by him, with him being very hands own since the beginning till at least the first F9. Just watch any fab tour with him, be the old ones from 2005 or the new ones at Texas.

He is also a founder at Tesla, as when he entered the round A financing Tesla was just three guys, some networking, and nothing more. Even the "Tesla" trademark and logo registration was made by SpaceX people. He didn't found his own car company with just J. B. Straubel (another Tesla founder who was being paid by him to develop electric car batteries at the time) because he thought it would be better to cooperate with that other group that was was inspired by the same idea and he though he would be able to concentrate more on SpaceX that way. He was wrong and had to take the CEO position on Tesla later to avoid bankrupcy, move the Model S design headquarters to SpaceX, etc. And it's now nothing like what it was when he first put money on it.

That's a nice find. I think BLS leisure time data is from the American Time Use Survey [1] which I think is asking something similar to this questionnaire [2] on page 22.

I'm not sure that's saying household time. For example, when they survey a household it wasn't clear to me if they survey everyone in the household or just one person. If it's one person then it sounds like they collect how that one person (age 15+) spent their own time and if there were kids in their household.

So then it'd be accurate to say that individuals in households without kids watch more TV as a singular activity (the survey doesn't allow simultaneous activities).

In comparison Nielsen used TV viewing diaries and automated data collection meters. You could have the TV on in the background while doing chores and it would still count.

It's interesting that the 2009 ATUS survey [3] had a 2.82 hour/person average because that's fairly different from the Nielsen data (4 hours 49 minutes/person).

I wonder if this difference is people underreporting in ATUS or Nielsen overreporting or a factor of differences in limitations in ATUS (no simultaneous activities allowed, 15+ age limitation) or Nielsen.

I hate his politics too but this is talking about planetary space lasers.

I don't think you can separate his ventures from him.

That’s a good point but I try my best because I love the ventures but hate racists.
