Since joining the corporate workforce, I've become truly terrified of smart people who are so smart that they recreate an entire separate field of endeavor. Poorly.
*Normal* people just ask software engineers to write fast math code, or web designers to create a nice customer-facing website.
*Smart* people say, "oh high-perf computing? Modern JavaScript? How hard can THAT be?" and spend a few several human-months and millions of dollars to make some utter piece of shit that barely works.
