I remember first playing with tech like this in the early 1990's. Q&A v4 from Symantec supported NLP and I was quite surprised at how potentially useful it looked, although as a developer I preferred more control. After typing your query, the app would display its interpretation of your request in more formal English to confirm it understood you. When there was ambiguity a few options were presented. You selected the correct one, and got your answers. It worked very well for queries like, "show me all employees hired after 2020-01-01 who's salary is greater than 80,000 sorted by salary descending".

Ultimately though, I think the usefulness of these tools breaks down for both complex queries and even simple ones when the data model does not have explicit relationships defined.
