One thing from experience having worked on a project 4 years ago, 2 of us spent a a couple of months investigating and coming up with a solution.

I tried it in AI and virtually did it all in a few hours! Magic?

Well I had gone through it to explore the problem space, and we had found a working solution which just petered out. But I still remembered the learnt lessons, and I was just eager to see what it would be like to use DuckDB on it.

My point being these second passes on projects often skip the hard won knowledge part.
