Do you think there is something innate that changed genetically about women that led to them being much less likely to be computer programmers now than they were in the 1970s [...]Wait – I thought back then (1950s/60s/maybe 70s), "programming" refered to something more akin to data input, i.e., someone designed a program, and the "programmer" entered that program into the computer's memory, using punch cards or whatever [1]. Later, this activity and the designing of a program was merged and done by a single person, as it is known today.
If this is true, then the mystery is not why women's preferences changed since the 1970s, but why their preferences seem to be different from men's, back then and today.
[1] You can still find this terminology in the hardware world. For example, storing the bitstream into an FPGA's SRAM or flash cells is called "programming the FPGA", and the little box which is sometimes necessary to do this, is called a "programmer" – which is kind of funny if you think about it.
