> People were in disbelief any of this was even possible.

Maybe my memory is that bad now in my old(er) age. But at that point in 2015, React had been a thing for about 2 years already. Ember had components even earlier than that in 2011/2012. Using components generally was a pretty well-accepted pattern from my recollection. The wars between the frameworks were all centered around render performance rather than APIs (i.e. which virtual DOM was best? do you even need a virtual DOM? etc.)

Not taking anything away from knockout per se, more just gut checking my own understanding/remembrance of that dark age.

I read it as "were in disbelief that this was even possible [in knockout]".
