I watched this video when it first came out. Honestly, the video is right in what it was trying to say. That said, that video didn't change my mind on whether to build on Dioxus and it should not for someone either.

The choice of framework should not be dependent on who else is building on that framework. Ideally the factors that matter: 1) Why are you building a GUI app on rust? 2) Target platform/OS support? 3) Are you ok with custom styling methods? Would you prefer to use CSS? 4) Need for multi threading? 5) Publishing / bundling / signing app

I think the reason Dioxus cadence release is slow is that they realised so many things are missing with the rust gui ecosystem that they decided they needed to fix these while building the main product. Guess what, this basically slows down your main product cadence. Does rust need a sub second hot reloader? Yes. Does rust need a native html/CSS renderer? Also probably yes. Did the Dioxus team have to take it on given their size and all the things pending in building rust with html + css? Armchair observer me thinks not.

*Note that I am currently building an app with Dioxus, so I'm putting out my honest opinion, and not saying that you shouldn't use it.*
