The concern is that a quantum computer could potentially be able to derive a private key from a public key. Which, if you expose your public key (as with old bitcoin P2PK wallets), would present an issue. If you're following best practices with regards to treating your xpub and other public keys as, well, not public, there's not really much there.

And in any case it's concerns for future decades, about hypothetical technology that may not ever actually exist.

To put it succinctly anyway. It's not something that is suddenly an issue; it was being talked about on the Bitcoin Talk forums back in 2012.
