Because literally 90% of developers today are wholly incapable of producing the cutting edge performance Figma requires. It's an engineering marvel. It's like wondering why more people can't just compete in F1. Money and talent at the rarest levels. Most companies engineer at the performance level of Atlassian. Which is not remotely sufficient.
where can i read more about the engineering behind Figma? Is it not just a UI for rendering polygons? Is all the technology in getting high performant rendering on top of a javascript engine? If so that doesn't seem like anything that crazy.
