Because it's vaporware, like UFOs and flying cars. Smells just like that BS cold fusion crap from 30 years ago. https://cen.acs.org/articles/94/i44/Cold-fusion-died-25-years.html
Maybe I'm wrong but I doubt its true. I was a Chemistry Major at UCB from 1987-1991 and Superconductors were the big rage back then -- although it was in Inorganic Chemistry not Analytical Chemistry. Ytterbium amalgams were the rage in the early 1990s but you needed extremely low temperatures to stablise it. Stanford even had a research center studying Mag-Lev technology for use in Trains, but it never went anywhere. Very similar to the research project I worked on in college for Buckyball (named after the famous Architect Buckminister Fuller), which was suppose to aid in the transport of large molecules inside the body but it never panned out either. [Buckyball is mainly found in carbon rods or some diamond mines. It is considered stronger than diamond.]
There is no one universally accepted physical theory of how high-temperature (about 35K and above) superconductivity works. So a true room-temp 1 atm superconductor may be discovered quite accidentally even if no one quite understands how it works. And IMO the best chance would be that it would work on boundaries of mixed materials as described for this one. The material seems to be fairly easily produced so independent confirmation (if true) should come quickly. If nothing is heard within a year or so, it's a dud.
Canada admits people based on a point system. "Top talent" will score high under their points system.
C60 still seems popular among the supplements crowd. https://www.sesres.com/why-c60-in-o...jz3UEQi93U8QO5YHXaq7X7k1JBkdVyNxoCGh4QAvD_BwE
Point System yes, everything else you said is not true. The point system exposes a huge bias toward young age above and beyond rewarding experience or skillset. No 20 year old has garnered any type of skill set nor advanced education and experience. Yet a 20 year old gets more points than a 40 year highly skilled ai engineered with a PhD or masters degree, all else being equal. Such 40 year old highly skilled person, with perfect English score, 2 masters degrees from top US schools, and 20 years of professional directly related work experience hardly garners enough points to meet the minimum threshold simply because points for age count for so much. That's a direct message sent to prospective immigrants that skills are not a priority but rather uneducated cheap labor that performs menial work once arriving in Canada and buys stuff and bids up housing.
