No: https://en.wikipedia.org/wiki/Post-quantum_cryptography

I agree with you that the statement is overly broad, but the person is referring to asymmetric cryptography in the past tense, making me read it as not about PQC because PQC is indeed the fix for the stated problem but must be applied first and until then, indeed we've always known QC are going to be an issue that needs solving.
Thank you, I did

However I was also unaware of PQC, which has been an interesting rabbit hole for the day

PQC is very immature.
Generally true, but Google has started using the stuff in production: https://cloud.google.com/blog/products/identity-security/why...
But its still bleeding edge. Its been used for experimental purposes but always in combination with a traditional algorithm (so if its broken the traditional algo still secures things). Its definitely not trusted yet.
Yes, which is what google is doing if you read the blog post. They wrap PQC encrypted message with x25519.
