Someone claimed they used fiber optic drones [1]. So perhaps the drones were connected to the trucks via optical fibers and the trucks carried the modems. That way, jamming over the airbases would have had no effect.

> you're telling me it's possible to be functional enough to eat and sleep for a week, but not know that your wife is dead and the barking dog needs food and water

Absolutely, in late stages of Alzheimers you’re a vegetable, but basic bodily functions still work to some degree.

Common sense means taking the less risky option.

Assuming that the survival rate is constant as a function of trip length, the empirical estimate of the risk is fully determined by the number of deaths per distance.

I’m not a vegetarian or animal rights advocate, but an argument could be made that cruelty to non-human animals is similarly normalized in today’s world, perhaps seen as a necessary evil to satisfy our appetite for food or fashion items.

Assuming a bedroom with surface area of 50 m^2 and an insulation R-value of 2 m^2K/W and an outside temperature of 30C, 300W would be required to keep the room at 18C. Cooling down 8 billion such bedrooms would require 24TW, which represents approximately a 10% increase in global power consumption.

Certainly a lot, but doesn't seem "catastrophic" and is realistic with today's technology.

Do the cows know they are herbivores? Why would the fact that they don’t predate on other animals in the wild make it “abhorrent” to feed them animal products in captivity?

TLDR: no evidence is presented for automated terminal attack capabilities. Even a heat-seeking missile is more automated than these drones which simply maintain course.

You’re right! The trapped ion approach (IonQ) is the most promising direction toward scalable quantum computing. Superconducting qubits — such as those used by IBM and Google — require extreme cooling while ions can be trapped at room temperature. Superconducting qubits are also plagued by substrate imperfections, while trapped ions — being “nature’s qubits” — are absolutely identical in their quantum mechanical properties. This allows trapped ion quantum computers to realize the best demonstrated gate fidelities.

Is there any evidence that Ozempic causes more muscle loss than what is to be expected from caloric restriction? I haven’t seen any.

You’re confused about what “statistical parrot” means and you don’t seem to understand the difference between an optimization objective and the resulting model.

The term “parrot” is used to imply inference by something akin to a look-up table, specifically it is used to indicate poor out-of-sample performance and a lack of a proper world model. The optimization objective is irrelevant when determining the generalization performance of a model and when judging whether it can reason beyond looking up answers in a table.

As the user above noted, it is now quite well established that GPT-4 has impressive out-of-sample performance which can be explained by it possessing an actual model of the world and not being a “parrot”.

The vast majority of people enjoy drinking and do so responsibly.

I absolutely respect people who drink in a measured way to enrich their life, instead of trying to maximize their lifespan by some minuscule amount.

We've been able to get a one- or two-dimensional control signal from average brain activity for a long time. This is infinitely more simple than actual "mind-reading" and "mind-writing" which, as any neuroscientist will tell you, we don't have clue how to do.

I just used the chat to cancel my subscription and they waived the early-cancellation fee without any issues. Maybe its some sort of damage control.

Fig. 15 shows results for a single sample, I believe.

You're right, an easy fix for this is to live and work outside of metropolitan areas where you get the same standard of living for a fraction of the cost.

Free speech is not really a thing in Germany (e.g., until very recently, insulting foreign heads of state was a criminal offence). Our ruling class absolutely resents the fact that the German people may have a channel for at least somewhat uncensored communication. Unfortunately, we don’t have a first amendment that would put some restrictions on their lust for control and power.

Wikipedia says they are. However, the Supreme Twitter Council of Wokeness may have ruled otherwise at some point.
