Current Use
Use of punched tape today is rare to nonexistent. No systems built new today still use punched paper tape. In CNC machining applications, what few existing installations remained in grandfathered use are now quickly disappearing as the temporary advantages for new orders of old part designs (i.e., not rewriting programs or retooling machines) are being superseded by natural economic evolution (fewer such orders as decades go by; part design revisions required reprogramming anyway; newer, higher-capability machines now successfully poaching the orders; etc.).

Famous quotes containing the word current:
“The current of our thoughts made as sudden bends as the river, which was continually opening new prospects to the east or south, but we are aware that rivers flow most rapidly and shallowest at these points.”
—Henry David Thoreau (1817–1862)
“I have come to believe ... that the stage may do more than teach, that much of our current moral instruction will not endure the test of being cast into a lifelike mold, and when presented in dramatic form will reveal itself as platitudinous and effete. That which may have sounded like righteous teaching when it was remote and wordy will be challenged afresh when it is obliged to simulate life itself.”
—Jane Addams (1860–1935)
