This sentence is proof of why you can't trust some blockchain promoters. For over 30 years, there has been an international standard for the (secure) exchange of electronic business information - EDI - Electronic Data Interchange. IBM has been a key player in the development of this standard. For example, here is a link to a 1991 European Patent owned by IBM dealing with a method to make it easier for businesspeople to use EDI: https://patents.google.com/patent/EP0507717A2/en
(and there are thousands of patents dealing with EDI from the last 30 years)
One part of the EDI world is an ANSI standard for electronic bills of lading: ANSI X12 EDI 211.
So the only honest comparison that IBM should be making is comparing the efficiencies/security of a blockchain-based bill of lading with an EDI bill of lading. But no, IBM companies a blockchain bill of lading with the centuries old technology of paper bills of lading. That is a dishonest business economic comparison, because it is one of the few ways to justify blockchain role in anything - via false comparisons. Indeed, one of the defects of many blockchain articles/books/talks, is the lack of mention of (secure) EDI. Dishonest.
