That seems like a particularly strange statement, it's hard to see how
tcpct has any impact.
On the time-scale you mention though; one conceivable change is that
as network transmission and server capacity become cheaper and cheaper
commodities, a tipping point will come when the best architecture will
be for eyeball-side endpoints to communicate with all possible server
The least-latent response can be used where interaction matters,
consensus can be checked where coherency and security matter, and
faults tolerated without the need for aggressive retries.
In other words; when the network is so cheap it no longer seems like
waste, client software will probably start to resemble today's
advanced recursive resolvers.
