This is not really a problem introduced by the thing in the article, but the "UI" for duckdb just kinda sucks. When I want to interactively explore some data, I want to easily add conditions and aggregates, but there's nothing in the Duck UI that actually does this. It will make a little table of the top 20 values of irritating_column_name but there's not a 1-click way to add `where irritating_column_name = 'incredibly inconvenient value'` to the query and re-run, which is an absolutely basic data exploration feature.
