Its viewed as such.

Aren’t those just standard door knobs?

Exactly, those two are pretty standard.options.

As far as door latches go the cross bar and draw bolts probably predate it by thousands of years but I don’t use those regularly.

As physical tech:

• we have lever door handles at work and wheel and axle door knobs at home.

As digital tech:

• Comma Separated Values as a notation predates computers. Then CSV has been used as a computer file format at least since one of the Fortran variants added support in 1972.

• The implementation has changed as filesystems evolve but the basic directory/file model of data storage and the associated tools ls/dir, cd, rm/del have been around a while. ls has been known by that name since Multics in 1969, but can trace its lineage back to listfon CTSS in 1961.

Anything that predates copy/paste is doing alright.
