There's not been enough time or data to support any argument at the moment as to what new TLDs are or are not going to do or be. We all just speculate, and "IMO" anyone who states otherwise hasn't fully understood the bigger picture and focus only on one aspect. Because it suits their argument, or eases their worry over their own investments (which of course we can all be guilty of).

That can be argued for both .com and new TLDs, at the moment...
So the post you made is about a heated topic in domaining at the moment. "Is .com dying out" - "new TLDs are taking over the world" etc etc etc...
It came across as unresearched in that you simply compared one single and miniscule aspect of the domain name market and made a bold statement from it. Perhaps you weren't totally serious, but others are as this kind of thing gets re-churned in different ways quite frequently.
There are always anomalies in domain sales, exceptions to the rule - sales that make all domainers ponder over how such a name was sold at all let alone for (eg) 5 figures.
Some of the new TLDs do sell. wine.club went for 6 figures, but look at all .club sales and you start to see a broader picture - in that sales are (mostly) only premium keywords, single words, and ones which mean a lot to specific companies with deep pockets.
I don't have any personal care for .com, I have no reason to defend it, so I say this unbiased - .com is king in terms of most sales across the board of niches and industries, and deeper level sales like 2 and 3 word keywords.
It's not that I hate any TLD, I just see the sales. If I buy (eg) a .com with 2 decent keywords that match and are fairly well known to commerce, then with the
humongous pool of domains and buyers and sellers out there I have a good chance of selling it in .com. Whereas in the new TLDs the sale is less likely because commerce hasn't yet embraced these new TLDs.
Putting aside the few (tens/hundreds of thousands) sales, .com is still what people understand and, whether an unnaturally created economic value or not, it is the most valuable of them all. Stats and figures and the marketplaces and reports show this, without doubt.
I own new TLDs, but I accept they're more of a gamble, a whim, than a sure bet of a pretty good two word commercial .com that many businesses will want.
And many people use the argument "but look at these sales in .whateverTLD" - no-one's saying non .com domains don't sell, they're saying that across the broad spectrum of niches, keywords, and possible domain names, .com sells way more than any other, and (arguably) easier if good keywords.
namebio.com shows a basic picture for those that care to look. Sure private sales will happen all the time so it's not perfect, and members here do well with new TLDs and private sales, but it is without doubt a harder sell - or even a lower value sell for keywords in whateverTLD vs .com for the same keyword(s).
IMO
