I have nothing but respect for Figma's tech, but I'm not really sure this lesson is generalizable to 99.9% of other people. By all accounts Evan Wallace has skills and talent the vast majority of software developers don't have and never will have. The reason Figma was able to succeed in this space is that their engineering team was like the 90s-era Chicago Bulls of software development.
And to emphasize, that's one reason I'm very happy for Figma's success. Figma didn't succeed because they "got lucky", or just happened to be in the right place at the right time, or had great marketing. They succeeded because they were able to create a brilliant technical solution to a problem that lesser engineers and engineering teams were simply not able to solve.
