I don't think Woz has done that kind of work since the 1980's at the latest.
Everyone knows the x86 architecture is inelegant. The 1990's saw a number of new CPU architectures being introduced and marketed to replace it, but none of them could keep up with the performance of x86. Apple fought that battle for the longest, up until PPC petered out. When they gave up and adopted x86, Macs became that much more useful for their ability to dual-boot Windows, or to run Windows in a VM. Apple was able to ignore some of the rougher parts of the PC architecture by avoiding BIOS and MBR.
