Yeah most of those are out of context and heck the last spindle drive I got was 10TB, but still people even with a well bloated Windows 10 install could get away with using a machine with only 100GB. The closest to an actual statement was Microsoft saying you didn't need more than 640KB of ram. But that was missing the context of the time. Their OS wasn't multitask capable and was really a 8bit OS at the time, so no application could actually address more than 640KB of memory making people selling systems with more pointless.
Job's on the other hand basically allowed the growth of Android by deciding almost unilaterally that they had found the perfect form factor for smart phones and that they were not changing. The context for that statement was recognizing a push for bigger screens and growing sales for those phones, that they were refusing to change because it's all people needed. The truth could be buried in there, that they didn't want to have multiple production lines for different sizes along with different storage, that they figured a person wanting larger would settle for smaller as long as it was "iphone" but that wouldn't work the other way. But he was pretty clear of what he meant and why he was saying it.
Either way at the time it wasn't far fetched. To take a quote from years ago and be like "omg" is out of context IMO. It is just as bad as all the things I mentioned.
