Is he for real?  The two most important innovations completely dismissed as not being for real photographers.  Content-aware fill is marvellous for filling in bits that are missing due to using rotation, perspective correction, etc. - see the Russel Brown video.  Puppet-warp is brilliant for correcting distortions such as volume anamorphosis when using ultra wide angle lenses.

He does come across as having a very high opinion of himself.

In his defense, Mr. Johnson is an avid landscape photographer and his site views photogrpahy from THAT perspective. He probably has little use for puppet warp or content-aware fill. Neither do those who value his opinion.
