Slightly more than half (55 percent) say quantum computing is a somewhat to extremely large threat today,
with 71 percent saying it will be a somewhat to extremely large threat in the future.

I read through your linked pdf...

According to what you've posted, that's 55 percent and 71 percent of Enterprise IT.

It is NOT 55 percent or 71 percent of "experts", or "knowledgable individuals", or "educated individuals".

Furthermore, according to what you've posted...

"59 percent, of those SAME "Enterprise IT" individuals, claim to currently be deploying hybrid (PQC + RSA/ECC)
certificates"

This is:
"something that is unlikely as PQC certificates availability is limited to early testing
situations"

Furthermore:
"71% say they are 'somewhat' to 'completely' aware of PQC, but thats not the entire story. We followed up with a question designed to test if they truly understood what PQC means. Less than two-thirds knew the correct definition."

Clearly, your reported "55 percent" and "71 percent" aren't exactly what I'd call "reliable sources". Their opinions about the threat of quantum computing aren't very compelling.
