What would be nice is a universal video call app. Right now, we have multiple, incompatible systems, such as Hangouts, Duo, Skype etc., where users of one can't connect with users of another. When we make phone calls, we don't worry who the phone company is, or send emails, we don't worry about the ISP or email app. Perhaps with the move to WebRTC, we'll eventually see this happen. It would also be nice to see Hangouts & Duo rolled into one app, so that it doesn't matter whether the other person has a phone or not when you try to contact them.
I haven't lost my mind. It's around here...somewhere...
