The bottom line is that if it is computable it will be computed, therefore make it un-computable. As in one-time codepad ? There is nothing new about this, those have been around for minimum 60 years afaik. Besides tempest and such used on one of the ends. The only new thing is crypto companies betting their maths against the speed with which entropy and other people's math and computers catch up with their products imho. If they catch up slowly then they have a good product which sort of auto-expires. I like this as a business concept.
