Why would I need to use events when I can access a contract's variables through the automatic accessor functions?

Please explain the use of and/or need for events.

No, not exclusively for real-time updates.

Events are inexpensive, well-organized storage, so there are many possible uses.

Have a look here, for example. How can we retrieve the evolution of the state of an smart contract variable?

In my opinion it's a good habit to emit events that describe all state changes in the contract.

Hope it helps.
