The person you initially negatively responded to said "networking is not the bottleneck," and if it's possible to have a meaningful negative reaction to that, it might involve asking "the bottleneck in what system?" I think he's right, but it's a blanket statement and it's fair to ask for more context.

More context: typical network latency is good enough that video games rendered on a remote server are becoming practical, or at least salable. "Network latency is high" is a vague enough statement that it could mean anything, but if being able to render video games remotely and stream the output to the client doesn't make you reconsider, I question what you would ever consider network latency that's not too high.

The kicker with these games, that perhaps speaks to the original, crazy post by horsawlarway, is that it's normal for a TV set and set of controls to introduce a lot more latency than the network connection itself: the network is not the bottleneck. There's a good excuse for the latency in involved in networking, rooted in physics, but this is not true for the hardware and the software stack.

Well, yes, I recently worked on the video receiver component for Stadia on Chromecast. So I know a little about these things.

Perhaps you can see why that makes your comments all the more baffling? It's understandable that you might view the network as a UI bottleneck since you were working on an application that relies maximally on low-latency networking, but you must realize how unusual that is, and how fast typical networking actually is in order to make your work possible at all. (and to the original point, how lame an excuse network latency is for those who can't manage to cobble together a fast implementation of a much, much simpler application)

It's just round trip to Europe from North America (esp western north america) is actually ... an eternity, could easily drift into 100ms -- and not one I can optimize to get rid of. Whereas I can work my way down the software stack and find bottlenecks and deal with them.

Yes I can't control what TV manufacturers do, that is a wild card. But the quote taken out of context is more than a little inflammatory -- the network has a hard physical limit that the local device does not.

FWIW I'm just as dissatisfied with software bloat as the next person. Retro computing is one of my hobbies, and the latency measurements there are something to be envious of.

ChromeOS generally does better in latency measurements than other platforms; much effort was made there, much of it by people I know.
