You mean in the 1980s? Linux wasn’t used before this wasn’t a concern for sysadmins and DBAs. This concern has been raised for years - back in the PowerPC era the numbers were lower but you had the same arguments about whether Apple had made the right trade-offs, or Linux or Solaris, etc.

Given the extreme rarity of filesystem corruption being a problem these days, one might conclude that the engineers who made the assumption that batteries covered laptop users and anyone who cares about this will be using clustering / UPS were correct.
