I'm not so convinced that it provides significant speed or ergonomic advantages.
At the population level, minor improvements can add up. But the cost of switching is high, also.

So... "typing is only improved if you actually learn to type"?
This "article" is a whiny blog post with exactly the same empty content that is always repeated and absolutely nothing new or of any substance. Total drivel.
And yes, I'm a 2-decade Dvorak touch typer. If there were something better I'd use that instead, but haven't found it yet.
