Nation states have been pouring billions into QC. It's hard to collect the varous announcements into clean figures, but rough estimates are that the US has allocated ~$5B to QC computation research, the EU (via the EU itself, and individual member states) have allocated more (closer to ~$10B-15B), and China has allocated a similar amount (again in the ~$10B range).

Industry quantum computing has made precipitous progress in the last few years, leading to industry companies (e.g. Cloudflare) to upping their personal targets for transition to 2029. You can read their motivation in the first few paragraphs of the following

We are currently in a place where it is entirely plausible that nation states will have quantum computers capable of breaking EC crypto (and RSA, although paradoxically it is mildly harder to break quantumly due to larger data sizes) by 2030. This is not guaranteed. But there have been increasingly many warning signs.

Maybe you don't care, and want to bury your head in the sand. That's your prerogative. But cryptographers do care, and so are taking all of the above very seriously.
