Trading halts are done automatically by the exchanges anytime any stock falls by a certain amount within a certain time frame. It’s meant to interrupt automatic, algorithmic high frequency trading from a runaway out of control feedback loop - think of it like muting the microphone when the speakers start making that high pitched feedback screech. Give it time. If there’s any justice left in the world it will be a penny stock by the new year.

That’s just straight up factually incorrect. From the link:

As a storage technology, Silica offers volumetric data densities higher than current magnetic tapes (raw capacity upwards of 7TB in a square glass platter the size of a DVD), and using beam steering of the laser beam, we’re able to achieve system-level aggregate write throughputs comparable to current archival systems.

Probably M Disk as others have said for consumer use, but Microsoft is working on storing data in glass that could last for potentially 100,000 years +. Not that you’d ever likely have that in your home. Although, maybe by 2100 we will, who knows. https://www.microsoft.com/en-us/research/project/project-silica/
