Observations of an Internet Middleman (Level3) (was: RIP

Blake,

I might agree with your premise if weren't for a couple of items.

1)  Very few consumers are walking around with a HD or 4K camera today.

2)  Most consumers who want to share video wouldn't know how to host it
themselves, which isn't an insurmountable issue but is a big barrier to
entry especially given the number of NAT'ed connections.  I think this is
much more of a problem than available bandwidth.

3)  Most consumers who want to share videos seem to be satisfied with
sharing via one of the cloud services whether that be YouTube (which was
created originally for that use), Vimeo, or one of the other legions of
services like DropBox.

4)  Finally, upstream bandwidth has increased on many/most operators.  I
just ran the FCC's speedtest (mLab not Ookla) and got 22 mbps on my
residential cable internet service.  I subscribe to one of the major MSOs
for a normal residential package.
