Good idea - reference numbers accumulate, don't reset every chapter
- p21 Turing guessed every Enigma encrypted message contained the words "Heil Hitler" ... a crib, not so identified in the book
- p23 Artificial neuron - summed "data' and threshold
- p27 1970, Life magazine reports Marvin Minsky claimed AGI in three to eight years in 1978 integrated transistors cost $0.05, and a human brain has 600 trillion synapses, hence $30 trillion dollars per AGI. US GDP was $2.4 trillion in 1978. In January 2025, I spent $80 for a terabyte solid state drive, two bits per transistor, hence more than $20 per trillion transistors, $12K for 600 trillion transistors. NOT synapses, which are routed de novo in a much more random way than RAM cells ... that multiplier is likely to be enormous. A corresponding "divider" is the much faster speed of transistors, though that SSD drive SATA interface moves only 4 gigabits per second.
