That is one of the big problems in encryption.

For a lot of data it is not enough that the encryption is secure for
1 day or 1 week or 1 month - it may be required to be secure for
10 years or 50 years or 100 years.

If encrypted traffic get captured today it can be attempted
decrypted in N years.

And some data are still sensitive after N years.

Name, SSN and DOB does not change.

Email address, phone number, bank account, passwords
may change or they may not change over N years.
