I agree here. This fellow looks like he is good at self-aggrandizement to gather shekels shucking ultra expensive software. I don't like this giant list of pedigree either. Solve problems or help others solve problems. To be fair, mathematica helps others solve problems BUT:
The licensing model is extortionary, its rental software, and it even tries to limit the users by how many API calls are made per month.
Also as others have pointed out because it is black box software its not really auditable.
I find a man who has made as much money as him being as greedy and self aggrandizing as he is today to be petty and money-lusting.
His book is roundly and rightfully savaged in reviews, check them out on Amazon. I will not be linking to it as this guy doesnt need more money pouring in.
I have a startup where our algorithms guy pays the mathematica fine every year. But lets be clear, algorithms guy does 99.9% of the work here and a good part of that is perspiration.
Wolfram just cashes checks - so with all due respect, lets not put this guy on a pedestal.
