As someone who dealt professionally with security issues from about 2000 onwards, many involving Flash 0-days, I have about as much fond remembrance of Flash as I do for polio or smallpox. I regard it as an infectious scourge that humanity has finally largely eradicated, and we're healthier for it.
As someone who used browsers in 2000 I have the same fond remembrance of JavaScript. Yet for some reason it still spreads like aids instead of following flash on its way out.
