Everything is just something else

Have been pondering AI and after my friend's presentation about The Conscious Mind I realised that I actually do believe that todays'a AIs have experience in some sense. However, that doesn't really have any straightforward implications regarding ethics or reasoning about its likely impact. My friend once told me about how her grandpa would always tell everyone to turn around to give his dog privacy while it shat. This was presumably tongue-in-cheek but if you do consider it as a serious viewpoint it's nonsensical: dogs do not have a socialised preference against being seen shitting. When you say a language model "wants" or "believes" something you make a similar mistake but of a much higher

In my upper-middle-class British education, having opinions was not only a sacred right but also the solemn moral duty of the well-educated. You could (and must!) engage in debate when you disagreed with somebody, but the sacred-right aspect meant that only a small and well-enumerated set of opinions could truly be criticised. Lacking convictions was a sign of intellectual weakness, but it didn't really matter which convictions you held.

This table visualises the space of eBPF opcodes. It was generated by this hack

The *s represent opcodes that are exposed but not actually used, or used internally but not exposed

Note that there are gaps, but no empty columns.

There's also a prettier version here
