The overwhelming majority of software ever written is fucking terrible and causes more problems than it solves.
Since software is easily copiable and mutable, that small sliver of good software gets replicated all over the place and serves as a foundation for other software, both good -- and at the risk of repeating myself -- and mostly bad.
People would be better off considering new tech as the tool it is rather than seeing every piece of software as inherently better than the thing it replaces.
