Two minor details I disagree with (in an otherwise very interesting and entertaining article): > In the 1980s and 1990s home computers didn't use much electricity. No-one cared about "thermal design power" In fact, Apple DID have a notorious prior brush with thermal issues: https://www.tekrevue.com/apple-iii-drop/ https://www.tekrevue.com/apple-iii-drop/ > When Apple abandoned the PowerPC they temporarily took a step back into a predominantly 32-bit world with the Core Duo, only fully embracing 64 bits a few years later, with the Core 2 Duo and OS X 10.7. As far as hardware is concerned, Macs with 32 bit Intel processors only shipped from January (iMac) to November (MacBook) 2006. I did wonder at the time whether gaining a few months was worth saddling software with i386 slices for several years (system frameworks had to be built for 4 different architectures, for instance). It's true that full 64 bit software support took a bit longer to emerge, but that may have been due to the need to support the 32 bit Intel Macs that were shipped.
