Last mile times are always going to cause lag. 5g won't be rolled out for years, then you'll need a phone to take advantage of it so that's not going to help. Last mile in US performance is really poor unless you're on full fiber which isn't offered in most of the US. Even with direct peering to the ISPs, which they don't have, this isn't likely to be a superior experience compared to a local machine. They'll have to push the entire video stream along with the intelligence. That's a lot of data that can't be lagged.
No. I don't not believe they've done this. They don't peer easily or often and peering with local partners is not something most people want to do, even Google. It takes trust on the part of the local service provider, which Google hasn't built as Google is often a direct competitor to their local products. Peering at the ISP level is really hard because it's all relationship management. Google couldn't manage their own fiber and built up a good deal of animosity with other networks in doing so, especially in the US.
Interesting information. There's definitely a bit of marketing going on there, but it seems that they have at least some peering. Without concrete public evidence otherwise I'll concede that Google must have great peering.
From a network administrator's point of view, they're an absolute joy to work with too.
If you're share any IXes with them at all, they'll peer with you. Private / appliance based peering has additional requirements, but that's par for course.
