Just imagine if someone experienced was retained at Intel told them that they are doing CPU level security wrong by doing downright idiotic things like sharing caches. What is the value of that worker in terms of productivity? Similarly with stripe, I am aware of dozens of similar companies doing CC processing that failed, and stripe probably built a better answer after sleeping on the advice of grumpy old advisors while companies that lost everything in recreating with nothing new had no advice or chose to ignore it. The general problem is that absurd hope may get you an IPO and a worse is better solution that experts can fix for you later. Building and maintaining a good company is hard and requires expensive experienced workers that lower your quarterly productivity by telling you the truth. Software being in the crisis it is in is no surprise, but the speed that hardware is joining the negligence for productivity club is more alarming.
