Thanks for taking the time to read and reply to my story! It's much appreciated :)
Btw, it seems like everyone has got the hunch that I advocate using strings as primary keys. That's not the point of this article.
The point is solely that there's an alternative approach to generate entity IDs - one that doesn't require the need for a database to wipe out IDs.
Also, it's entirely possible to have entity id and primary keys as two separate columns in the database.
