I have a question. What does it mean for AIXI to be the optimal time bounded AI? If it's so great, why do people still bother with ANNs and SVNs and SOMs and KNNs and TLAs and T&As? My understanding of it is rather cloudy (as is my understanding of all but the last two of the above), so I'd appreciate clarifaction.

Are you familiar with Big O? See also 'constant factor'.

(You may not be interested in the topic, but an understanding of Big O and constant factors is one of the taken-for-granted pieces of knowledge here.)

You mean that horrible Batman knockoff? I hated it.

Yeah, I know what Big O is.
