Probably Flash. * HTML5 has widespread support amongst all new browsers and mobile platforms. * Silverlight will probably move on to embedded corporate applications or atleast that is how microsoft has described it. Plus they have the funds to bankroll it for a decade. One thing about Microsoft, either they kill it early or kill it very late. There are some platforms that have lived long past everyone forgetting they ever existed. * Flash is going to be fighting a shrinking pie of mindshare. It won't happen right away but once it reaches a tipping point these things go really fast. So the question should be which is dead first?
