Re: real challenges still facing human civilisation – regulatory compliance.
so says someone who clearly has never read a regulatory requirement - while there are some areas of compliance which are very clear cut, there is a lot of it which is littered with principle statements and words like "appropriate".
by way of example can I direct you to SYSC 13.7 "Systems and Processes"
and in particular 13.7.5 which deals with IT systems.
I doubt machine learning can deal with those high level requirements that I just referenced, but even at the specific end (e.g. required disclosures for retail sales) it would be extremely hard to write a general case ruleset in a traditional linear logic fashion.
