My two cents: i don't think tech is a stable 9-5 nor for stable freelancing. It's very short term and unpredictable. What is stable--- is policymaking in the tech sector. However, writing, speaking, etc have been in one form or the other for centuries. This article is missing the point of how long term industries and a business plan matter. Another long term industry is real estate, the same for copywriting. Always weigh what is the next 100 years of what you're doing.
