DSL turbocharging schemes remain just that

DSL Renaissance Underway?: Zero Touch Vectoring
Vectoring technology is a relatively new innovation for DSL which basically is a noise cancelling technology which reduces cross talk in copper pairs, allowing DSL to achieve much faster bandwidth throughput as a result. Some vendors are claiming they can squeeze 100 Mbps out of VDSL2 vectoring, albeit at rather short distances. It’s very much a FTTN technology, where VDSL2 connects to the home from a fiber fed cabinet.
These stories continue to appear year after year as vendors hope telcos will adopt their latest sooper dooper DSL turbocharging scheme.  Problem is while telcos aren't investing FTTH CAPex, they aren't investing CAPex or OPex in their aging legacy copper cable plants either and are instead concentrating on the mobile wireless space where more rapid ROIs are to be had.

And the above reference to "Zero Touch" for many telco customers has an entirely different meaning: DSL won't touch their premises because the DSL signal can't propagate far enough over old copper to reach them. Zero Touch=Zero Service.
