You can only get so far as a pastry chef knowing the recipes. Understanding the chemistry does take your craft to a higher level.
I’m never really surprised that there are so many security vulnerabilities out there. Tons of software is completely half-assed: slow, error-prone and inefficient. The market supports it because VCs keep pumping out companies that throw spaghetti at the wall until something sticks. And it has had an influence on the kinds of skills we optimize for at the hiring level.
