(That verbiage lasted most of 2013, but was removed a couple days after this capture, presumably because payments were starting to become less "instant.")

Bitcoin has literally been presented as a replacement for cash payments since day 1. I could go on, and on. That history is now being rewritten, and I think it’s important to understand why. Bitcoin set out to do one thing, is failing at that one thing, and I’m discouraged to see people rewrite the narrative rather than own it and say it didn’t work for that.

And you've mixed up your history: the research grants into the Internet were funded for that purpose, but it quickly morphed into an alternative usage once the new abilities were seen. Nobody went out and pulled out full page newspaper ads with that intent for its design, or otherwise heralded the Internet as such.
