You're missing the point. GP was mentioning the common assumption that all systems in the last 30 years are sector-atomic under power loss condition. Either the sector is fully written or fully not written. Optane was a rare counter example, where sector can become partially written, thus not sector-atomic.

This assumption was wrong for Intel Optane memory. Power loss could cut the data stream anywhere in the middle. (Note: the DIMM nonvolatile memory version)

"huge opportunity in German mechanical engineering". Ha. He should compare a modern German car, with their 2-3 year warranty, to a modern chinese car such as BYD, with their 8 year warranty.
