If electrons move at light speed, then why do computers operate so slowly sometimes?

If chips and discs use electrons to transmit, store and read information, and electrons can move at near light speed, why does a computer function so slowly sometimes? Can’t it process all the information within an indiscernible time duration without causing any visible lag? What causes the clog?

This is not the same scenario as Internet lag, because I searched in this subreddit and found answers that on the Internet, numerous small time intervals across the globe can accumulate and make a great mess, even at light speed. This question is relevant with local computing.

Imagine you could lay bricks at the speed of light but I asked you to build a tower to the moon. It would take a while. It’s tens of billions of bricks. And every brick close to the moon would take you over a second to get there and another to come back to earth for another.

Simple computer functions are made up of millions of instructions at a physical level. And they compete for space.

It adds up.
