Can someone who understands AI explain what we don’t know about it?

I’m a user researcher with a background in HCI delving into tech ethics and I’m trying to understand how I should feel about this. It’s a new technology and it’s here to stay. There are various issues that we have not fully figures like algorithmic biases, accountability, security etc. I’m trying to understand specifically just how blind are we stepping into this. Is it something that we depriotise while building or so we not fully understand the technology and it’s ourself? While there are a lot of studies on the impact after something is built, how much are we able to predict while building it? Apologies if my phrasing is too confusing, happy to clarify pointers.
