I hate to be a broken record,
but are people reading the original article?
The title of the article is
The Rise of Alternative Domains
He goes on to explain that he means alternatives to .com, and the success of the various country codes that have found wider use.
All of the examples he gives are country code. All of them!
In the article he mentions, often multiply, domains with these extensions .io, .tv, .me, .ly, .et, .to, .ai and .am.
How many new gTLD extensions does he mention anywhere in the article? 0 (yes zero). He does mention briefly that he could see new extensions finding a role like the country ones did, where you could buy them hand reg 10 years ago and now they have value (that is how he made his $1 million plus profit).
So someone barely out of their teens figures out a domain strategy that leads to $1 million dollars profit. He has built a business around it for 10 years. Sure disagree with his ideas, complain about the cheap shot that
@equity78 correctly calls him out for, but at the very least I think you owe it to the author to read his article to see what it is you don't agree with.
