Honestly, having used both extensively at different points for years I can say that I understand his approach for smaller projects, but Typescript coupled with coding standards, makes working with large teams and large code bases 1000x better. Being able to immediately know what data is being passed where at a glance is invaluable.

I hope I never have to work with this person. What a shit take.

I think the best take on this is from Rich Harris at Svelte. They are dropping it for internal Dev because they get the same feature set from JSDoc and have no build step, but they keep it for Svelte users who want TS.

Fuck DHH. Fuck his shitty racist blog posts that he inter mixes with inflammatory bullshit that he does to the rails community.

Rails needs him gone desperately

Cool, Typescript is basically useless.
