No one I know likes using Teams, they're forced to. I also temporarily used teams for a previous startup and we switched back to Slack. Basic things were broken, like search, which is a no go from me.
I like VR, am an enthusiast even, but if that's their representation of "potential", I think we're headed down the wrong path. I understand the spirit of Teams having everything integrated and available, but in practice they will have to do far better in user experience and functionality, it's not enough to say you have a feature, that feature has to at the very least not suck in the software world, in the VR world? It better blow people away. Most people are still highly skeptical of VR and they will need to be amazing.
