tell me if im being dense but ...
"As recently as 2012 we had a near miss solar event that could have shot society back to the 1800s, instantly rendering our power grid and all electronic devices useless."

"Therefore, we should hypothesize that these magnetic field disruptions could eventually disorient the magnetized bits that store our civilization’s data on computers and electronic devices all over the world.
If so, let’s hope that miners and others safeguarding Bitcoin and its blockchain data implement preventive measures against these cosmic threats. For example, they could install strong magnetic shielding to protect data storage devices and ensure the implementation of effective data backups”
surely if we were set back 200 years and all electronic devices are rendered useless it'd be pretty pointless to still have bitchains blockchain or any other
Such set backs due to solar radiation would only be temporary, it is not inconceivable that power grids could be back online within weeks the only problem remaining then would be if enough ppl had backed up blockchains and priv keys on some sort of non magnetic storage ie optical disks.
