Funnily enough, this same year (1999), I wrote an essay for a university AI subject where I concluded "Intelligence is a label we apply to information processing for which we have not yet identified an algorithm. As soon as an algorithm is discovered, it ceases to be intelligence and becomes computation". I thought I was very clever, but later discovered that this thought occurs to almost everyone who thinks about artificial intelligence in any reasonable depth.
This would imply “artificial intelligence” itself is a nonsensical term… as in “artifical [label we apply to information processing for which we have not yet identified an algorithm]”.
I dunno, the opacity of LLM’s might kind of fit the bill for not having an “algorithm” in the usual sense, even if it is possible in theory to boil them down to cathedrals of if-statements.
