Willy Woo tweeted that you also need to protect your public key in the coming era of daunting large quantum computers. Basically, large quantum computers can derive your private key from the public key. Today's Taproot addresses (the latest format) are not secure, these addresses start with "bc1p" and they embed the public key into the address, which is not good. The previous format hid the public key behind the hash value, so large quantum computers cannot easily crack it.
