Glad to break my run of four DNFs over the preceding 4 weeks. Was suspecting alzheimer's had set in.
Had a slow start with several tentative fills to indicate unparsed clues, but in the end threw them in and began to parse most of them. 6d 'here' is still a mystery, as noted elsewhere.
I'll offer that if AI is going to save the world, as we're all promised, it needs to get a bit smarter. I asked it for operas with four letters. It gave me one four letter opera and three five letter operas. And not the one I actually wanted to confirm my guess. So I had to rephrase it as 'look here matey, is xxxx an opera or not' to actually get confirmation.
