If you are paranoid about the outcome of this US sponsored competition to come up with encryption standards, then you should be paranoid about Bitcoin's SHA256, Tor or anything else that came out of US related activity.
In any case there's no real reason to worry about any of this, quantum computing as it is today it's just a meme. I would stick to SHA256 and plan for a NIST alternative in the future if necessary.. and non-US stuff doesn't necessarily mean safer anyway. It just has to be peer reviewed by as many independent and widespread people as possible.
Satoshi most likely did the right thing at not using something more exotic, it could have backfired, SHA256 was the most widespread with hardware support and timetested, peer-reviewed by cryptographers.
This being the anniversary of the september 11th World Trade Center attacks. It should be remembered that the official report attributing the destruction of buildings to office fires was drawn up by NIST (National Institute of Science and Technology). The 9/11 report NIST released was NOT open to peer review by architects, structural engineers or anyone with the academic or professional credentials who might normally peer review that type of report.
Not only does NIST have a history of publishing controversial findings as their initial 9/11 publishing containing "pancake theory" was wholly debunked by engineers across the globe. They also have a history of producing work that is completely closed to peer review or any form of accountability process.
Quantum computing is pseudoscience imo. There is no real quantum computing threat or crisis aside from media gaslighting and sensationalism. What we're witnessing is the typical process by which crisis is artificially manufactured to push agendas.
