With front-end development getting increasingly popular, I think backend is starting to become just a thin wrapper around database. If database can be securely locked down enough, a lot of business logic can be shifted to the front-end.

Unless "locked down enough" includes "with all the business logic embedded in the DB", this is going to fail in exciting ways with technically-savvy users...

Then you can't use it across apps, though.

Say for example you have a web front end, a mobile app, and a service receiving web hooks that all want to execute the same action. If you have that in a client layer, you'll be writing it 3 times.

Moving logic to the client comes with pros, too (like being easier to work offline), but it definitely has downsides as well.
