The art of conversation includes moving between each, and pulling a phone out every few minutes stunts that normal conversational flow.
There is also the problem of what is a fact (Alaska is part of the United States) and what is a "fact" (e.g. Covid came from bat soup in a wet market, Russia's invasion of Ukraine was "totally unprovoked" etc.) Discussion is the entire point in those cases, since we can't trust our entire set of "facts" anymore thanks to censorship.
I think you're missing my point. They were both presented as facts and discussion online was (and still is in the case if Ukraine) presented as such. The only way to move past those types of bottlenecks is through discussion. "Looking it up" will likely give you an answer that doesn't pass the sniff test in a normal discussion.
