The boom has to do with Audiophiles buying these $7000 :"directional" ethernet cables:
The reviews are worth a look for the giggles, too
Global spending on Ethernet cables will soon cross the $1bn threshold, say analysts. A forecast report from Allied Market Research projects that by 2022, businesses will be shelling out more than a billion dollars annually on copper and fiber cables to transmit data and power. The figures include the spend on fiber and copper …
Memory density on flash drives is sufficiently good to actually be able to get good overall throughput on a homing pigeon. The birds can average over 90 mph, and rack up 700 miles in a day source. A 45g terabyte memory stick shouldn't be a problem. The RFCs   might need a bit of updating, though.
Latency is a bit of a bugger, and "packet" loss can be catastrophic.
QED - a story from 2009 - let's hope things have improved since then
"SA pigeon outpaces broadband"
A Durban IT company pitted an 11-month-old bird armed with a 4GB memory stick against the ADSL service from the country's biggest web firm, Telkom.
Winston the pigeon took two hours to carry the data 60 miles - in the same time the ADSL had sent 4% of the data.
Telkom said it was not responsible for the firm's slow internet speeds.
The idea for the race came when a member of staff at Unlimited IT complained about the speed of data transmission on ADSL.
He said it would be faster by carrier pigeon.
If that were true, telephone cables (ALSO usually copper) would still be the same quality they were in the past, but a funny thing called corrosion tends to factor in. So in the long run, copper CAN get more fickle. Not to mention copper is relatively valuable so is prone to getting stripped out of the ground.
Europe was also tabbed as a strong market, particularly in the industrial sector where growing connectivity of appliances means larger networks and the need for cables
The industrial sector needs fibre, rather than copper. I ordered fibre 35 years ago, those sites are still running fibre, in really hostile conditions. The price of fibre to copper converters with PoE injection is dropping all the time.
Even a small switch needs 10/40 GB uplinks, and "campus" deployments should not link buildings using copper, if only to keep the insurance company happy.
I expect lots of disasters in China (not gangnam ( OK Seoul), but, Lightning Style).
