I heard Elon is trying to sell Twitter. Wanna buy it?

Okay. I have a question. Is Taproot Upgrade is Smart Contract? How Taproot upgrade helped Bitcoin? I am puzzled after reading some articles. Maybe it is because I am not understanding how it works. One article said the Taproot upgrade enables verifying multiple signatures at once. Another article said it's a smart contract upgrade. How it's related to SegWit? Wasn't SegWit upgraded before the Taproot upgrade? SegWit departs the signatures data. The block already contains more data after the SegWit Upgrade. So, what Taproot did do?

Arrrrrggggggg 😡
