There's no such thing as "intelligence in one area", intelligence is a general ability. You're basically ignoring everything that psychology has studied regarding intelligence.

That's probably one of the reasons why you'd use GPT-4 to explain GPT-2. Of course, if you were trying to use GPT-4 to explain GPT-4 then I think the Gödel incompleteness theorem would be more relevant, and even then I'm not

The Stargate SG-1 TV series has a similar, although not exactly identical, recurrent plot point (replicators). The show is well worth watching IMHO.

You probably don't even need to have the server in your premises. Perhaps the server could be in some datacenter and you, as well as others, could use it remotely via the Internet.

It's very rare and extremely interesting for me to read a well-argued opinion that is the polar opposite of mine. Furthermore, I don't even have any good counter-arguments (at least not any that wouldn't just be pure speculat

The Flying Spaghetti Monster is also an interesting concept. It can even be useful as a concept, in certain discussions/contexts. Should we take the Flying Spaghetti Monster as a core axiom of our theories of physics? Wouldn't thi

That's very interesting, thanks. So you're saying that in such a scenario, it would be impossible for complex life to exist, even if it looks different from the complex life we have now? I am just wondering whether we are not conf

I can't really give a substantial response to your first argument, as I'm not certain about all the implications that you mention. Your second argument, though, doesn't sound very convincing to me. There are many possible con

What does the 'single' profile do in btrfs? I thought it was equivalent to RAID-0 mode, but apparently it isn't, because they are separate options and btrfs switched from RAID-0 mode to 'single' mode by default, alt

Yes, that's true. However, even if you're not using ECC RAM, you're much better off using ZFS or btrfs, because due to their frequent checksumming and checksum validations, these filesystems will usually detect memory corrupt
