I have very fond memories of Wave. My non-tech friend group embraced it as our primary communication platform for a brief period and it hosted a frenzied chaotic fun that was only matched over a decade later by the tech exuberance of AI image gen and LLMs.
It was too early.
The UI was slow due to the browser not being able to handle it. A new Wave with top performance on phones would have a chance of becoming a thing.
