To me the craziest thing about this is that often times web apps with the same functionality feel leagues faster to load, with nearly equivalent functionality.

To me the craziest thing about this is that often times web apps with the same functionality feel leagues faster to load, with nearly equivalent functionality. Google docs/google sheets/notion/coda all load faster than the native MS Word / Excel. Photopea is another example - it clones out the main user paths of Photoshop and loads in a 1/10th of the time. I really don't understand it.
