Everyone has to start somewhere, but if you don't know what ZIRP stands for you just don't have the fundamentals/haven't taken enough interest in economics to participate in a conversation related to macroeconomics and posting grumpy comments out of ignorance won't help you. You're going to have to read up on it.
Although FWIW you probably aren't a bot, an AI would likely know all about ZIRP.
I recommend against books; they're expensive and typically the page count is too high for the number of ideas unless you are really interested in the academics of it. I get a lot more out of Wikipedia [0], blogs and YouTube (although the quality of information on YouTube is typically low).
That being said, if you want some recommendations I'd suggest Tyler Cowen [1] as a good clearinghouse for topical ideas and John Cochrane [2] as an interesting read. I picked an article from the last 7 days where you can see the ZIRP in the graphs, it is all the points where US Fed Funds rate was at 0.
It really wasn't, but it did assume the audience was familiar with a specific bit of discourse about, well, ZIRPs. In particular that when debt is super cheap, companies can afford to do a lot of things that would be stupid when capital comes at a higher price. Which generally seems to have been true about a lot of SV companies.
