AI doesn't replace thinking or intuition. It's just a tool. it is good at identifying patterns. It can process a lot of data fast which can be quite useful.
I find it very helpful by using it interactively where I do most of the thinking and it adds polish.
For example, writing a user manual, or press release, etc.
I start writing with an idea, it wordsmith's much faster and usually better than I do.
I then reedit its response and repeat the process until I get results that I like.
Passive crossovers are well established. You might be able to use AI to automate the process a little, don't expect it to invent a new kind.
Modern DSP solutions also use building blocks, but offer many more practical opportunities for differences. AI probably isn't going to tell you what is best, but perhaps it may be able to tell you some kind of consensus based on a data. Of course, if enough people say it on the Internet, it must be true, right?
I have posed tech questions to AI where I knew the answer already. AI makes mistakes that may not necessarily be where you expect.  In my tech question example, AI explained the process precisely and correctly and then proceeded to solve the math wrong.
I pointed this out and it even agreed with me (politely).
Lesson is that AI is not infallible and is often wrong - Remember when directions from Google Maps would tell you to drive into a lake?
That said, most of us use Google Maps regularly, and it is usually quite good. AI is getting better as well.
