I'm having trouble believing network latency would be the bottleneck here. Just ping google.com and you'll see ~25ms latency which is a lot less than the half second delay described in the article.

Now, having the server actually process the information, and return a response that then must then be vocalized may take much longer, but that's a different issue than "network latency".

Not to mention when people interact, they often use filler words when collecting thoughts... "um...", "uh...", "hmmm..", "yeah...". there's your half second delay

Pinging is a lot different from sending data. Its not just about words but also your actions. Try uploading an image to Imgur or a video to youtube! Humanoids probably have to do them. So entirely on the cloud is certainly not possible. Maybe do some precomputation on the humanoid and send the data for comparison with a larger dataset to the cloud makes sense.

You're talking about bandwidth, not latency.

What are you talking about? People live stream to YouTube all the time. And to Twitch. And they used to on OnLive. And Nvidia has a thing. And Skype. And Google Hangouts. And Chatroulette.

Most of those services have a lot more latency than you may realize. I've been looking for a way to stream real-time game video from a friend on the west coast to me in Kentucky, so we can kibitz over voicechat; high-quality streaming video has very noticeable delays at best.

(And it's really bad if the service is optimized for streaming to many viewers at once--Twitch enforces a minimum buffering delay of 10 seconds even for a private, one-viewer stream, and can range as high as 60 seconds in heavy conditions, which really annoys a lot of streamers. If anyone has a suggestion for a good low-latency one-to-one video streaming tool, I'd love to hear it...)

NVidia GRID is probably the best benchmark, especially since a latency optimized data center full of GPUs sounds like a pretty good place to do some matrix multiplication. If it's fast enough to play a game it should be usable for everything but fast motor control.

Have you tried using the webrtc protocol? It streams data without a go between server. You can probably find a website that implements screen sharing, if not its like 100 lines of JS.

Did you ever play twitchplayspokemon? The latency between sending your command in the chat and it appearing on the stream is about 20 to 30 seconds.

Isn't that because you're voting? As in, the delay might be intentionally built in, to give votes a chance to come in.
