On the other hand, malleable systems are responsible for enormous increases in the productivity of computer users. We may all hate kludgy excel spreadhseets with a nightmare of tangled hacky VBA code, but you see that sort of thing in a lot of businesses' critical workflow because that kinda of malleability by "untrained" users was invaluable in the earlier life of the business.
It's still invaluable in highly locked-down office environments. It lets users automate things that they wouldn't be allowed to automate otherwise (needing a full development environment or the ability to run arbitrary executables or access to Powershell).
