There's a ton of money made off flash these days. No one's saying you have to use it, but lets be a little realistic with ourselves.
Partly works now if you don't need much control over it, or if you do work on the server to split the media into chunks. Full streaming support in progress, see WebRTC and other ongoing work.
> socket connections
See WebSocket, which has gone through some initial hiccups but otherwise works fine.
> fast 3d
WebGL provides 3D which runs as fast as the user's system can handle.
> advertising
Don't care. "The web still has ads?" But for the sake of argument: iframe, javascript, arbitrary web content just as capable as any other webpage.
> webcam support, mic support
In progress. http://www.whatwg.org/specs/web-apps/current-work/multipage/...

And on a related note, https://developer.mozilla.org/en/HTML/Element/input#Image_ca...
> clipboard manipulation
Already exists in JavaScript, just blocked in modern browsers for privacy reasons. Needs to become another grantable permission, like geolocation, but I suspect it just hasn't become prominent enough on the radar yet compared to other features.
> install base
By definition smaller than the install base of web browsers. The proportion continues to decrease as mobile devices become more widespread.

https://www.youtube.com/html5, http://www.engadget.com/2011/07/16/pandora-radios-html5-rede..., github only uses it for the clipboard, never seen flash on flickr, imgur, or google docs, the web still has ads?
"Partly works, recent hiccups, runs on good hardware only, in progress (aka not here yet), blocked, smaller install base..."
I am all set for Flash to die, but I am not sure the web is QUITE ready for it to die yet. Replacements are coming quick... but the operative word is "coming". I look forward to the day it's all really here and ubiquitous as Flash is/was.
I intended my post to summarize the ongoing work on the replacements for the various things people cared about in Flash, specifically to make it clear that HTML does have all the same use cases in mind. As each new technology becomes available, more bits can migrate off of Flash.
Flash needs to start dying now, so everybody on the sinking ship can start figuring out what they need and solidifying the replacements. It'll have a lingering death scene, so the sooner it starts, the sooner it finishes. If the replacements don't work, they need fixing, without people thinking "oh, I'll just use Flash instead". People need to think "no, it needs to work now, I need to migrate off of Flash as soon as possible".
Ideally, in the next couple of years, we'll get Flash to the point that Java has reached now: an oddity that the occasional legacy site uses.
uploader piece with progress bar and other small components. just cos you don't see it doesn't mean it's not there.
imgur, for instance, seems to have an excellent HTML5 image uploader and editor.
I realise WebSockets does what it does for security reasons, but i do prefer Flash's method of getting around that (remote server hosts an XML policy file on a separate port) since it doesn't interfere with the connection in any way.
Once, this trouble is sorted, WebRTC looks goody.
3D graphics directly in the browser has been talked about for well over 15 years, http://en.wikipedia.org/wiki/VRML for example Java for another.
