Sigmoid

After his colonoscopy, Tom learned that he had cancer. The surgeon cut out and removed the part of his sigmoid colon in which a tumour had been growing, and with staples she fashioned a new splice from the two shorter and cut-through ends. Because of his good health, he healed quickly and after only three days was discharged from the hospital.

Systemic and local hygiene has supplanted drugs and surgery in the treatment of diseases of the anus, rectum, sigmoid flexure, and vermiform appendix.

If we had the textbook from a hundred years in the future that contains all the simple ideas that actually work, that take so long to identify in practice — the ReLUs instead of sigmoids — for those of us who’ve been following AI for, like, more than the last couple of years and know what I’m taking about there.
