I have to admit, arguments over free will never interested me all that much, because if we don't have free will it's something of a moot point. Might as well "choose" to have it.
What I am interested though is the potential involvement of quantum effects in consciousness. I'm not particularly sold on any of the existing theories, but at the same time, I'd honestly be kind of surprised if consciousness didn't involve some sort of quantum effect, now that we know they can be exploited by living things--photosynthesis, and possibly smell, though the latter seems rather controversial. It may just be bad reasoning associating two notoriously difficult problems, though.

Imagine LLM do chip decapping and perform fault injection on hardware and extract firmware. I think Cyber securiry is bigger than that. I think that take another few decades until we get there and once we are there it is not anymore just cyber security jobs.
For more than 25 years, a technology used for critical data and voice radio communications around the world has been shrouded in secrecy to prevent anyone from closely scrutinizing its security properties for vulnerabilities. But now it’s finally getting a public airing thanks to a small group of researchers in the Netherlands who got their hands on its viscera and found serious flaws, including a deliberate backdoor.
German researchers gained rare access to three satellites and found that they’re years behind normal cybersecurity standards. A new analysis from a group of German academics provides a rare glimpse into some of the security weaknesses in satellites currently circling the Earth. The researchers, from the Ruhr University Bochum and the Cispa Helmholtz Center for Information Security, have examined the software used by three small satellites and found that the systems lack some basic protections.

Abstract: Satellites are an essential aspect of our modern society and have contributed significantly to the way we live today, most notable through modern telecommunications, global positioning, and Earth observation. In recent years, and especially in the wake of the New Space Era, the number of satellite deployments has seen explosive growth. Despite its critical importance, little academic research has been con- ducted on satellite security and, in particular, on the security of onboard firmware. This lack likely stems from by now outdated assumptions on achieving security by obscurity, effectively preventing meaningful research on satellite firmware. In this paper, we first provide a taxonomy of threats against satellite firmware. We then conduct an experimental security analysis of three real-world satellite firmware images. We base our analysis on a set of real-world attacker models and find several security-critical vulnerabilities in all analyzed firmware images. The results of our experimental security assessment show that modern in-orbit satellites suffer from different software security vulnerabilities and often a lack of proper access protection mechanisms. They also underline the need to overcome prevailing but obsolete assumptions. To substantiate our observations, we also performed a survey of 19 professional satellite developers to obtain a comprehensive picture of the satellite security landscape.

I am really disappointed with Sandy. While other guys are professional, Sandy to me seems too much biased. He was not like that. Sad.
Truth is required to act freely. Freedom requires knowledge, and in order to act freely in the world, you need to know what the world is and know what you’re doing. You only know what you’re doing if you have access to the truth. So freedom requires truth, and so to smash freedom you must smash truth.
Part of what fascist politics does is get people to disassociate from reality, there is no truth, there is only opinions. You get them to sign on to this fantasy version of reality, and from then on their anchor isn’t the world around them — it’s the leader and his opinion.
