Flash ah aaaahhhh!
So we're told again and again that plugins, like Flash, are evil security threats that must be banned and will be blocked entirely after 2020 to save us all from their malicious intents... Only for them to be replaced by basically the same thing (but no doubt implemented in half a dozen ever so slightly different ways by each of the major browser makers, like HTML5, to ensure you need to implement the usual array of workarounds and polyfills)
