I thought it was fairly clear - using the browser for an offline database is dumb. Even worse, by propagating this sort of nonsense it encourages new devs to think thats how things are done, when you can do the same thing with a native app, 10 or 100 times faster and take perhaps a tenth or even less the time taken to develop it.

Edit: and as I said at the beginning - "I often feel I'm on another planet" - having this discussion with web developers trying to justify something that is not just bad but dumb in so many ways always gives me a chuckle, and I try to educate on why there are other things beside browsers, and its not a very good way to write software
