One of my favourite aspects of history is seeing how historically important events were perceived at the time. Often, I feel like those events are today misrepresented, focus misplaced or overemphasised, but I don't imagine an easy way to more accurately represent them, and don't care. What I love are things like Tim Berners-Lee's proposal for what would become the web being noted as "vague, but exciting":
In March 1989, British physicist Tim Berners-Lee wrote a proposal to develop a distributed information system for CERN physicists and engineers. It described a way of managing information about the accelerators and experiments at the laboratory using a system of documents linked together and accessible via the internet. His supervisor, Mike Sendall, wrote “vague, but exciting” on the cover of the proposal, and, with those words, gave the green light to an information revolution.
