I've been programming for 30 years, and getters/setters are both pointless and anti-productive.

They hide (potentially a lot of) code from people reading the program, which leads to a lot of "wtf" moments later.

Magic in general is bad, and it's the kind of "look how concise and clever I am" thinking that leads to unmaintainable software.

If setting a property isn't straightforward, make it private/protected and add explicit getter/setter methods. It's more work today and much less work later on.

The only sibling comment of yours that bothered to even show code just demonstrated how they turned user.lastPost into a method that makes a hidden DB query.

Yet the benefits are supposedly so nuanced and hard to get across that merely asking about it gets a "you'll understand when you get some real experience ;)" comment from you.

That's fine and okay.
