this is exactly the kind of post that folks who say "oh - it wont take our jobs - our jobs are safe (way too advanced for silly AI)" - need to be reading. You're an expert, and it answered an expert question, and your colleagues couldnt do it either...after a few days...and this is just early days.
I don't think this is the take away. I'm in a similar situation as the GP, but the crux is that we still need people to make the decisions on what needs to happen - the computer 'just' helps with the 'how'. You need to be a domain expert to be able to ask the right questions and pick out the useful parts from the results.
I'm also not so worried about 'oh but the machines will keep getting better'. I mean, they will, but the above will still remain true, at least until we get to the point where the machines start to make and drive decisions on their own. Which we'll get to, but by that point, I/we will have bigger problems than computers being better at programming than I am.
I look at it differently. If what we've been writing can be replaced by a machine, that leaves us with coming up with more creative solutions. We can now spend our time more usefully, I think!
