I use AI a lot these days, and the funny thing is that it feels much faster, but looking back, new features seem to take roughly the same amount of time, and the number of bugs appears to be about equal. The main time-consuming issue seems to be finding the right balance between providing too little and too much information. Give the AI too little reference data, and it begins deleting what it thinks is unnecessary, or it simply starts overlooking things; give it too much, and it chokes. I do spend less time writing or copying and pasting boilerplate code, but in the end, double-checking and debugging AI-generated code tends to equal it out.
