Kessler syndrome relies on two key provisions:

1. Orbiting objects never try to avoid each other.

2. They're in high enough orbits that atmospheric drag is not a significant factor such that debris can last decades or centuries.

Starlink fails both as they constantly maneuver and they're in low orbits that are constantly cleaned by the atmosphere.

And I'd add that "kessler syndrome" is actually a statistical process, not a rapid sudden cascade of satellites crashing into each other. It takes years to decades for it to actually "happen". It's not something that can be caused by military action either.

Do you think Starlink is somehow extraterritorial or something? They're no more or no less a "private internet" than any other ISP. People need to get a reality check. Hacker news is becoming one of the most luddite places on the internet.

That's simply impossible. You must be seeing something else. They aren't that bright.

The post he was replying to is the reductionist and dismissive take.

And yes progress is good progress.

If you're seeing "strings" those are recently launched satellites. Operational satellites are below visual magnitude.

Starlink by itself does not have a net loss.

FWIW it may be tenable now as Starlink has gotten much better at tree/obstruction avoidance in the signal and will preemptively switch the satellite it's using when an obstruction is approaching. Id check again.

Companies are only going to do Level 5 self-driving unless they can own the vehicles.

You will never get a company to accept responsibility for crashes with hardware owned external to the company. I mean there's all sorts of things you could maliciously do to break hardware that you personally own. This is especially the case with something like Tesla where the people who absolutely hate Elon already go to extreme lengths to create news stories to attack him with.

There is just no advantage to the SAE level nonsense. It doesn't even make sense from a technical perspective as vehicles do not function based on "ODDs" (Operational Design Domain) that the SAE levels rely on for their definitions. The SAE levels were created by people who don't understand automated driving vehicles.

Part of the problem with Apple Vision Pro was the sales strategy. They labeled it "Pro" but if you went into an Apple store they only let you play some simple games and watch some movies with it. The main feature I was interested in, desktop extension, they wouldn't let you test. I even explicitly asked and they said no. They wanted a guided experience thing which just turned me off from buying it.

SpaceX/xAI is investing in creating their own fab. If they can, Apple certainly can.

What is of value to watch on any of the streaming platforms?

Netflix content is atrophying. Disney Plus is dying. To say nothing of Hulu or others.

I watch youtube. The content is way more varied and interesting and less sanitized.

FWIW, I would not trust LG here to actually do nothing even after turning all the elements off, their GUI is especially "web"-like. Just leave it disconnected.

I don't understand why people can't just get a secondary device for accessing live streaming programs. There's numerous devices you can buy that do it.

TVs should not be connected to the internet. The incentive structures are just too bad against the user.

Because social media is embedded into many apps.

Weird. I've shifted more and more of my social media use to X. Especially the last few weeks have been great with Artemis and an algorithmic accident that X's auto translation feature has been enabling tons of positive cross cultural communication with people from Japan. It's more fun than I've ever had on social media. Reddit on the other hand has been completely dying.

This has more to do with the UK government than a "for-profit company". Apple has been one of the biggest forces pushing back against this kind of thing forever, at least in the US where companies still have rights.

Google practically never shows explicit images to anyone anymore anyway. Even bing doesn't anymore. I feel like we've returned to a more prude society, at least on the mainstream internet.

I use Firefox and uBlock Origin but still pay for premium because I want to support the channels I watch but don't want to watch their ads.

I want to nitpick you here but a thermos is specifically good at insulating because not only does it have a vacuum gap, it's also got two layers of metal (inner and outer) to absorb and reflect thermal radiation.

That specific aspect is NOT true in space because there's nothing stopping thermal radiation.

Now you're correct that you can't remove heat by conduction or convection in space, but it's not that hard to radiate away energy in space. In fact rocket engine nozzle extensions of rocket upper stages depend on thermal radiation to avoid melting. They glow cherry red and emit a lot of energy.

By Stefan–Boltzmann law, thermal radiation goes up with temperature to the 4th power. If you use a coolant that lets your radiator glow you can conduct heat away very efficiently. This is generally problematic to do on Earth because of the danger of such a thing and also because such heat would cause significant chemical reactions of the radiator with our corrosive oxygen atmosphere.

Even without making them super hot, there's already significant energy density on SpaceX's satellites. They're at around 75 kW of energy generation that needs to be radiated away.

And on your final statement, hyperloop was not used as a "distraction" as he never even funded it. He had been talking about it for years and years until fanboys on twitter finally talked him into releasing that hastily put together white paper. The various hyperloop companies out there never had any investment from him.

Trying to make a point out of whether he did or didn't found Tesla kind if defeats the rest of your post. He paid over 90% of the first funding round and brought in key people like JB Straubel. When the company was basically an incorporation paper and no assets. Under most companies people would have argued for founder/co-founder status at that point. So yes he didn't "found" Tesla but for all intents and purposes he basically did.
