Funnily enough, they address this question on the linked website: > Whenever we work on metaverse or VR for Matrix (e.g. 3D video calling, or our original Matrix + WebVR demo) we always get a some grumpy feedback along the lines of “why are you wasting time doing VR when Element still doesn’t have multi-account?!” or whatever your favourite pet Matrix or Element deficiency is. > The fact is that Third Room has been put together by a tiny team of just Robert (project lead, formerly of Mozilla Hubs & AltspaceVR), Nate (of bitECS fame) and Ajay (of Cinny fame) - with a bit of input from Rian and Jordan (Design), Bruno (Hydrogen) and Hugh (OIDC). On the Matrix side it’s been absolutely invaluable in driving Hydrogen SDK (which also powers things like Chatterbox and of course Hydrogen itself) - as well as helping drive native Matrix VoIP and MSC3401 implementation work, and critically being our poster-child guinea pig experiment for the first ever native OpenID Connect Matrix client! In terms of “why do this rather than improve Element” - the domain-specific expertise at play here simply isn’t that applicable to mainstream Element - instead there are tonnes of other people focused on improving Matrix (and Element). For instance we shipped a massive update to Element’s UI the other week.
