Ask HN: Is real time the future and what fields still missing this feature?

Real time search, charts, products updates etc. Every field seems to have real time updates now. Although, it seems useful, do you think it has a future or what could there be something beyond real time?<p>The reason we put the question is because our idea of a startup is related to updates of transactions in real time. And since this was the area we could think of, we also would like to know if there is any field lacking real time feature.<p>We'll really appreciate your response to our queries.<p>Thank you.
