wowow

it is even hard for me to conceive or conceptualize or create a mental model of the notion of "different computers" working on the same thing separately

Shards are like splitting up a big job into smaller tasks. They're important because they let us handle huge amounts of data by breaking it into chunks that different computers can work on separately. 

For scaling up, shards are crucial. They mean we can keep growing our system to serve more users and store more info without everything grinding to a halt. It's like adding more workers to an assembly line - we can produce a lot more by dividing up the work.
