Continuity — Various statements about how soon the "organ bank problem" ended appear contradictory:
(a) "There followed a Golden Age— a period of peace and contentment for Earth and Belt— that lasted for two hundred and fifty years. In particular, breakthroughs in alloplasty and regeneration ended the organ bank problem" (interstitial notes in Tales of Known Space p. 135). This seems to indicate the organ bank "problem" was ended at the beginning of a 250 year "Golden Age"— which lasted until the first Kzinti attack on Sol System, circa 2384.
(b) Elsewhere, in describing a 216-year "Interlude" between 2125 and 2341, it is specified "A great many things happened in two hundred and twenty years... Improved alloplasty— gadgets instead of transplants— went a long way toward solving the problem of organ bank shortages. The UN citizenry even voted to remove the death penalty for certain crimes: income tax evasion, illegal advertising" (Protector p. 104). If the death penalty had been repealed for only two minor crimes, clearly the organ bank problem was not "ended" by 2341, only 43 years before the end of the Golden Age. Therefore it seems clear that if the organ bank "problem" was ended during the Golden Age, it was only in the last years.
(c) Following the invention of artificial organ replacement, it is said society on Earth began "...swinging back to what was once normal. Slowly; but there was motion. In Brazil a small but growing alliance agitated for the removal of the death penalty for habitual traffic offenders" (A Gift from Earth p. 11). It is difficult to pinpoint the time this occurred exactly, but the passage describes the ramrobot carrying artificial organ technology which precipitated a revolution on Plateau. From the description of the ramrobot’s journey, we estimate the ramrobot spent 13 or so years traveling the 11.9 light-years to Plateau. Using our date of 2341 for the revolution (see "Dating Notes for ‘The Ethics of Madness’ & A Gift from Earth" in the Articles section), the year of launch would have been circa 2328. But regardless of the exact year, this is another indication the organ bank "problem" lasted for most of the Golden Age, and also another indication the change was slow and incremental. ↵
