Not quite sure what the argument is here, but “already researching” is
severely behind the times. Multiple PQC algorithms are well past the
research stage, with finalized standards published in August and a
couple more on the way. Adaptation of higher-level standards (APIs, PKI,
etc) and adoption leading to deployment is well underway.

I’m not sure anyone thinks quantum computing is “almost there” in the
sense of e.g. a quantum computer big enough to break RSA existing this
year. However the risk is real enough to be worth actively mitigating,
both because we may not know when the first one is deployed and due to
the “harvest now, decrypt later” strategy.
