I'd be interested in the article claiming wifi is faster than ethernet in general. Ethernet standards currently support 10Mb/s upto 100Gb/s obviously it gets very pricey up there.
Low cost consumer cat 5e ethernet kit at 1Gb/s isn't realistically widely replaceable by wifi to my knowledge, I've read of wiGig 802.11ad kit supposedly hitting 7Gb/s but that is using the 60Ghz spectrum which wont go through walls and that's likely a very theoretical top end.

Any kind of wireless 802.11ad router will likely currently set you back at least £350 and from what I can make out on this arstechnica article 802.11ad appears to only match traditional 1Gb/s ethernet for download, when you have router and device on 802.11ad.

For example my wifi 802.11ac capable laptop on the 5Ghz spectrum with line of site to a Netgear 7000 ac1900 (£100) router is roughly a third to a half the real world download performance of my wired cat5e connection to the same router.
That said it's obvious the wifi gap is diminishing for home use, unless 802.3bz ethernet kit brings 2.5Gb/s or 5Gb/s (genuine) performance to our cat 5e cables at a reasonable price.

As I said the 10+ Gb/s ethernet kit is currently silly money for home use.
