I concur - dead air in person is much more palatable, especially if multiple people are engaged on the same (mental) task at the same time. The description you're giving there, of the performance, is one where only one person is doing that, so it's not 100% analogous - though in the context of TFA it certainly is (ie. 'group brainstorming'). Tangentially but related, John Ralston Saul had this to say (complain about?) on the subject of immediacy in the face of questions: "ANSWERS [are] A mechanism for avoiding questions. "This might be called obsessional avoidance or a manic syndrome. It is based on the belief that the possession of an education — particularly if it leads to professional or expert status and, above all, if it involves some responsibility or power carries with it an obligation to provide the answer to every question posed in your area of knowledge. This has become much more than the opiate of the rational élites. It may be the West’s most serious addiction. "Time is of the essence in this process. An inability to provide the answer immediately is a professional fault. The availability of unlimited facts can produce an equally unlimited number of absolute answers in most areas. Memory is not highly regarded. Right answers which turn out to be wrong are simply replaced by a new formula. The result of these sequential truths is an assertive or declarative society which admires neither reflection nor doubt and has difficulty with the idea that to most questions there are many answers, none of them absolute and few of them satisfactory except in a limited way."
