I don't think it has endured. Oliphant said that in ~1976, and said later he regretted it. (see the source article: https://en.wikipedia.org/wiki/Douglas_Nicholls#cite_note-Black-34 https://en.wikipedia.org/wiki/Douglas_Nicholls#cite_note-Bla...). Oliphant himself had an interesting life. He discovered the structure of Tritium, was involved in the development of the cavity magnetron (radar) during WW2, and kick-started the Manhattan Project.
