It's bad. I believe them not to use it for training, but t means relevant data can and will be exfiltrated by US agencies or through court orders (see NY Times vs. OpenAI, where only traffic without any rentention was safe).

Of course, should it be as cost efficient as claimed and if you don't use it but everybody else does, you might be pushed out of the market.

But electricity is under half (30%?40%?) and the rest of that energy isn't fossil-free.

The trick of course is that if you electrify heating and transportation they'll need much less energy. Your average car with an ICE has an efficiency of 20-40%, electric cars have 60-80%. Heating your house with gas has an efficiency of around 100%, heat pumps have 300%-500%.

If you were to design an entire ATC system from scratch (pilot interfaces, sensors everywhere in the airport and planes etc) it can be automated.

Even then you'll probably run into the long-tail distribution issues, similar to self-driving cars. 99.9% of all situations are pretty standard, but once in a while something so abstruse happens that it's not pre-programmed and requires some creativity to solve.

What you can probably do is create software which observes traffic and simulates it into the future and notifies the human ATCs about risks.

Fully agree. Some of the recent close calls really were "obvious" much earlier, meaning they were not caused by late course changes.

I use them as cheap-man's VPN. A ssh server on a public IP but a non-obvious port brings you into the network, and port forwarding allows you to connect to relevant endpoints in your remote network via localhost:12345.

My Weird Hill is that we should be building things with GPT-4.

Absolutely. I always advocate that our developers have to test on older / slower machines. That gives them direct (painful) feedback when things run slow. Optimizing whatever you build for an older "something" (LLM model, hardware) will make it excel on more modern somethings.

The thing is that your home's heatpump has an efficiency of 300%-500%. So even if your power plant and power delivery only has say 50% gas-to-electricity-at-home, you are still looking at 150%-250% gas-to-heat-your-house efficiency.

The "Elon process" relies specifically to the goal of getting rid of all dependencies. Musk has spoken extensively about building things from the ground up and not relying on other vendors (in this example complex software dependencies). He says he wouldn't be able to build SpaceX competitively if he had just bought rockets or components.

That I cannot believe. He might have shifted the make-or-buy decisions, but both Tesla and SpaceX do a lot of outsourcing.

Can you say what hardware could do better? I.e. which kind of primitives do you miss, or would make it easier to develop safer software?

Lightning detection. You have a couple of ground stations with known positions that wait for certain electromagnetic puses, and which record the timestamps of such pulses. With enough stations you can triangulate the location of the source of each pulse. Also a great way to detect nuclear detonations.

There is a german club that builds and distrubutes such stations (using GPS for location and timing), with a quite impressive global coverage by now:

Mandatory: We should build it in space and beam the electricity back to earth using electromagnetic waves. We could collect those using solar cells. And then get rid of the plant and use the sun instead.
