Think of it this way.
Blockchain, smartcontracts, 4th industrial revolution is all about automated contractual labor. Robots. yes seriously, these applications (smartcontracts) will be replacing pencil pushers much in the same way robots replace manual labor. Hence why we can use SC in Defi and banking and insurance, etc....
So, back to robots. A robot is only as good as the information it uses to make decisions. Chainlink makes sure the information that is fed to the robot is trusted and the Truth. It does this through its Oracle network. Not gonna explain it here but there is plenty of reading material out there for you. But, in short, the oracle network is the like the internet in which smartcontracts can tap into for data.
As Stani from AAVE put it. The larger Defi gets the more reliant that sector will be on Oracles. Once the total value of defi surpases ETH marketcap the greatest security, the greatest value will be in Oracles because all of Defi will rely on Chainlinks data.
And that is only one sector.
