To answer your question. Yes. Thousands of people are looking into this all day every day. From economists in academia to CIO's at every major bank to the motley crew of econ-conspiracy-theory bloggers.
Like many things in economics, data to study this is limited and noisy and just sucks. Lot of assumptions needed in the models and there is no historical precedent to bounce on.
TL;DR There is no consensus whether zero percent interest rates will turn out to be overall good, bad or neutral for the economy. To the extent there may be winners and losers, even details of that are still unclear. Any other answers right now are just speculating opinions.
My opinion at this point: I agree that ZIRP/NIRP do not work under the current business models that underpin our entire economy! (try it for yourself put a zero in a denominator of a fraction)... But I disagree this necessarily destroys the business models, maybe it does turn out very bad or maybe business models just change/fix the error as they were written poorly to begin with and things will be OK. Who knows.
