FWIW, I believe his opinion was that 128K was enough. My recollection is that he wanted that amount to run Multiplan, and that is why he talked IBM into using the 8088 instead of the intended 8080 for the IBM PC. I believe this because Radio Shack sold add on cards for various Z80 boxes they made so as to provide 128K for Multiplan (mainly).
