I do note that you conflate two distinct issues: whether touch-typing is worth learning, and whether Dvorak is a meaningful (or any) improvement over QWERTY. I am definitely far more suspicious of the latter claim than the former (see my link in the grandparent for a thorough debunking).
Even the studies cited by the author in your link show a speed advantage of around 5% for Dvorak over Qwerty. Considering my point of the 10k hours, the payoff is more than worthwhile, before even taking RSI into consideration.
On a side note, one of the reasons I decided to learn touch-typing was because I have some free time at the moment and was looking for something else to do than read blog posts all day, so I totally agree with you that investing 30-40 hours now might not be the best for everyone… TDT probably recommends it though.
