What if Steve Jobs lived during Guttenburg’s time? Jobs was an innovator and changed the computer, cell phone, etc. industries. His human capital and vision have affected how millions of people communicate on a daily basis. Likewise, the printing press prompted a major transformation of the book industry, which reshaped how people communicated.
I think one difference Jobs would have brought to early printing and books would have been fonts. Initially, they were bulky and difficult to read. Jobs preached simplicity so I think fonts such as this type would have been used earlier.
