Kurzweil said atomic weapons were invented when he was a small child, and that two nuclear weapons were exploded in anger within one week.

Claim: Kurzweil stated that when he was a small child, two nuclear weapons were exploded in anger within one week. True if the transcript/record of his 2024-03-29 remarks shows he said two nuclear weapons were exploded (referencing the Hiroshima and Nagasaki bombings, Aug 1945) during his early childhood, within a week. This is a claim about what Kurzweil said. Note Kurzweil was born in 1948, after 1945, so the 'small child' framing may be a factual slip, but the claim here is only that he said it. Mostly true if he said essentially this with minor wording differences. False if the record shows he did not say this.

   “We do have the nuclear power that evolved when I was a child.”

The criteria call for a transcript or record of Kurzweil's remarks on 2024-03-29, and none of the evidence is such a record. The closest item is a third-party transcript of Joe Rogan Experience #2117, dated 2024-03-12 (E1, E5), where he says "we used two atomic weapons within a week, 80 years ago." That matches the "within a week" detail but places the event 80 years back, not in his childhood. The 2023 Lex Fridman transcript (E6–E8) says the bombs went off in '45 and that none has gone off "through anger" since, and it ties only nuclear power to his childhood. Without the 2024-03-29 record, the evidence cannot show whether he said the bombings happened when he was a small child.
