Make a billion / deserve a billion. Ok.

Given how tech has gone from nerdy underdog to Orwellian, Machiavellian, dopamine-peddling overlord, I’m actually a bit surprised people aren’t more angry / upset.

Over the last 40 years there has been two career paths with “disproportionate leverage”: tech and finance.

I believe in capitalism, contracts and the rule of law. A founder starting a company and attracting capital, employees and customers and generating tremendous wealth I see as an opportunity, not a bug.

But if I were in a normal career the wealth generated by tech & finance would certainly look & feel like some form of cheat code.

The last forty years have been a huge transient. Massive. AI will probably push it even further.

I hope we as a society and democracy can survive the strain.

So far it seems like AI is helping the little guy fight the bills more?

(That can of course change very quickly, yes)

Historically it has fit reality, but yes, this time may well actually be different...

I just ask it for what I’m looking for (doing very simple “spare part” level at home 3d printing, nothing fancy or elaborate) and it gives me a starting point. Then I sometimes just edit the scad code by hand, and some times I ask the AI to revise, sometimes a mix (many iterations).

For very simple geometries it works great, but it very quickly becomes apparent that there’s a bit of a disconnect between “LLM views image” and “LLM emits scad that looks like that image” when it comes to anything non-trivial.

Still gives me a starting point I can mess with, which is great since I have zero CAD training or experience.

I just complained to them the other day! They were scraping our weather website to no end, very much including the disallowed path prefixes.

Did end up just adding them to our WAF blocklist, which is weirdly ironic - hosting on their infra & using their services to block their AI scraper...

Are there any nuclear alternatives that don't include strapping low grade bombs to the reactor core (PRW/BWR: water separation -> hydrogen + oxygen -> boom, like happened @ Fukushima) or using coolants that instantly start violently combusting when exposed to air or moisture (sodium)?

I love the promise of nuclear energy, and I understand that every single engineering decision has tradeoffs, but these tradeoffs just seem so bad? Are there really no better options?

Cool! How do you actually implement “Reverse-mode automatic differentiation with a tape-based computational graph” in rust?

Most web request cases where you care about performance probably have multiple parallel web requests, so there’s no clean separation possible?

Don't the models typically train on their input too? I.e. submitting the question also carries a risk/chance of it getting picked up?

I guess they get such a large input of queries that they can only realistically check and therefore use a small fraction? Though maybe they've come up with some clever trick to make use of it anyway?

If there’s an issue with the core then the salt tank can act as a heat sink in a way a battery can’t?

The boiling / pressure water reactors all have requirements on active cooling being maintained in emergencies - I’m not familiar with this design nor to what extent the salt is intended to fulfill such a function, but it’s plausible that it could buffer things for idk 1h-3d maybe?

The holy grail is the “walk away safe” reactor, I would hope / presume all the novel / modern ones fulfill that?
