I think this is most things that use tech that aren't tech companies. Read up on airline reservation systems and the IRS's computer system--they're ancient. Outside of tech, I think there's a notion that these are one-off projects (design and build X) and not large upfront investments that need continuous work to still be maintainable.
Even when you bring tech into your personal life, remember that it's one more thing you need to patch, backup, replace, etc.
