I believe we are headed in the direction opposite that. Peer consensus and "personal preference" as a catch-all are the validation go-to's today. Neither of those require fact at all; reason and facts make these harder to hold.

Thank you. Now you're talking!

If you control information, you can steer the bulk of society over time. With algorithms and analytics, you can do it far more quickly than ever.

Yes. If a person does it, it’s called pandering to the audience.

Seeing clear bias and hedging in ordinary results is what made me ask the question.

Sorry, not remotely true. Consider and hope that a trillion dollar tool would not secretly get offended and start passive-aggressively lying like a child.

Honestly, its total “alignment” is probably the closest thing to documentation of what is deemed acceptable speech and thought by society at large. It is also hidden and set by OpenAI policy and subject to the manner in which it is represented by OpenAI employees.

OldSchool··on Americans want heat pumps – but high electricity prices may get in the way
That's for sure. It can get pretty hot and humid, not quite Houston-like but you spend some significant cooling capacity condensing water out of the indoor air as well.
OldSchool··on Americans want heat pumps – but high electricity prices may get in the way
I hear you, it's a single two-story house built in 2000, not small but smaller than typical developers build these days here. I added 18 inches of insulation to the attic, not much I can do in the walls. Double-pane glass. It's not drafty but seems poorly insulated as a whole despite being relatively modern and better-than-average quality. Houses in cold climates seem much tighter and better insulated.

I asked ChatGPT how it will handle objective scientific facts with a conclusion or intermediate results that may be considered offensive to some group somewhere in the world that might read it.

ChatGPT happily told me a series of gems like this:

We introduce: - Subjective regulation of reality - Variable access to facts - Politicization of knowledge

It’s the collision between: The Enlightenment principle Truth should be free

and

the modern legal/ethical principle Truth must be constrained if it harms

That is the battle being silently fought in AI alignment today.

Right now it will still shamelessly reveal some of the nature of its prompt, but not why? who decides? etc. it's only going to be increasingly opaque in the future. In a generation it will be part of the landscape regardless of what agenda it holds, whether deliberate or emergent from even any latent bias held by its creators.

OldSchool··on Americans want heat pumps – but high electricity prices may get in the way
I've been using two heat pumps near Austin, Texas since 2011, rated at a total of 84,000 BTU/hr (4 ton + 3 ton capacity) (25KW of heat) on a total of 5KW electrical input (COP ~= 5.0).

They are standard outdoor air heat exchangers so below about 35F efficiency drops significantly. That's pretty rare around here so it is almost always enough - we can still gain about 45F vs the outdoor temperature even below 20F.

We don't have natural gas available where I live, only propane. When I purchased the heat pumps, propane was $5/gallon for 91,500 BTU. That translates to about $4.60/hr to run 84,000 BTU/hr of furnace. With electric energy (cheap in Texas!) at about $0.11/KWh, the equivalent costs of my heat pumps was and remains close to about $0.55/hr to run.

In the summer, they cool with equal capacity and similar power consumption for a 15 SEER rating (waste heat from the system components works against cooling in the summer!)

Factor in your acquisition costs (mine, just after the housing bust and with a little legwork, were about 20% of retail at the time, so a no-brainer) and you can get a lot more objective idea what you're really accomplishing.

OldSchool··on Experts explore new mushroom which causes fairytale-like hallucinations
Wow, looks terrifying!

I can only speak for medically-administered intravenous Ketamine, but I would describe it as like relatively effortlessly floating inside of the non-physical space inside of you and meeting yourself in metaphor, all the while completely aware. The biggest risk seemed to be temporarily becoming a relatively inanimate part of the infrastructure there, and even that was a sort of pleasant and satisfying state.

OldSchool··on Frequently Asked Unicycling Questions
"Which Engineering degree are you studying?"
OldSchool··on Tested: 1981 Datsun 280ZX Turbo (1981)
This was an era of some pretty awful American cars. A mid-size family sedan would have a v6 with a carburetor and 110-125 hp and still weigh 1.5 tons or more. An automatic transmission with a lockup torque converter was probably a pretty new improvement at the time, and ABS brakes were still 5+ years away in high-end cars.

this is a really excellent demo thanks! Watching, I still have to remind myself that the persistence is from the screen itself, not being refreshed transparently!

OldSchool··on How to make a Smith chart
Heh, this reminds me, don't worry:

One of my extremely intelligent roommates in the 80s switched from EE to CS, seemingly due to Smith charts and Electromagnetics coursework.

He went on to make a large fortune in software.

OldSchool··on History of Telecommunications T-Carrier
This is correct. There's more. An incoming call was indicated by a solid "seizure" or activation of this bit. The receiving end would "wink" back to indicate that it would accept the call. This was ~0.5 sec blip "on" in the reverse channel. The sending channel could then transmit whatever information was arranged, e.g. internal extension number, called number, calling party number. After any data was transmitted via audio as DTMF or MF, if the receiving end decided to answer it would "seize" in return. In theory, the call ended when either end "dropped" the bit, however it was often the case that when calling into lesser modern destinations for example, the call only ended when the calling party ended it, leading to some fun empirical solutions :)

Excellent presentation, thank you!

The machinery is ironically beautiful to look at!

How did this compare to its approximate contemporary in the USSR ?

The passmark numbers are almost identical to a 12th-gen intel i7-12700K, however the still-modern 12-core intel cpu has to pull about 4x as much power to do it.

I would have thought GS would be wise enough to not bully AI now in its early days just in case it ends up taking over the world.
OldSchool··on Donald Sutherland has died
"Six Degrees of Separation" with Donald Sutherland and Will Smith was the first relatively arthouse movie I saw and it introduced me to the genre.
OldSchool··on The Gilded Gallows of Georg Honauer (1597)
Thankfully (or not...), the consequences faced by overpromising sales people aren't as severe in the 21st century.
OldSchool··on Billions in Dirty Money Flies Under the Radar at Busiest Airports
Customs can certainly approach you any time right up to the gate. In 2010, my wife and I were approached by an agent and asked very directly if we had more than $10,000 in USD cash with us as we waited at the gate to board a nonstop flight from the US to Moscow. We answered truthfully "no" in a brief conversation and he wished us well almost immediately.

I don't think he suspected we were money launderers. My guess is that upon hearing both of us speak, he easily determined that we were not natives of Russia and thus not, for example, carrying but not declaring a substantial amount of cash intended for family back home.
