IMO ...
A smart person can know a lot about a lot of things.
An intelligent person knows how very little they actually know about most anything and how absolutely minuscule is their absolute knowledge of everything. That person may view everything as a game of Jenga; loosen the stability of one piece and the whole begins to teeter.
A somewhat less than smart person in any one arena believes it can all be taught in a few short lessons. They may not be "stupid" about anything, they simply do not utilize the thought process needed to see the interweaving of all things.
How many times have you begun research on a topic by entering a phrase in a search engine only to find you soon have a dozen tabs open to research topics you have found through your initial search? And, you realize you could continue to add another dozen with ease and still not begin to really know the topic you've started to research?
If you have not been taught critical thinking (here's a link for those of you not familiar with the term;
Defining Critical Thinking ), then you likely feel you can reduce most things to a few basic ideas and those few ideas can be taught to you by a smart person within a few minutes to a few hours.
If you are not familiar with the concept of first principles, then you likely feel all things can be reduced to the tools or equipment required to allow the results you desire.
It's actually how most of us shop for "stuff".
If you have no friggin' idea what a logical fallacy is and when you've waded into one, you buy more stuff thinking that is your way around the process of learning.
It's often the way we discuss our newly acquired "stuff".
On the other hand, it is very easy to study and research and to not know enough about what you should and what you shouldn't need at any one time that you waste a lot of time reading about what has no value to your immediate result. Self taught students of anything tend to bounce around to the next shiny thing without sufficient knowledge of or insight into the subject to know they don't need to know "that" at this time. That, IMO, is the value of a very good lesson plan, it keeps you on track by building a solid foundation before you start on the upper floors.
Etc. ...
It can, IMO, all be reduced to the simplification of our education systems and the marketing of the commercial product. Too many education systems have been reduced to a result stage which bypasses teaching critical thought processes. The teaching to the test process we find in many school systems. The answer in search of a problem path to achievement. All of which benefits those wishing to create absolute tests and those providing easy answers, all wishing to be judged by a set script vs thinking individuals.
Probably you've heard the phrase, "Knowledge is power".
Power does not reside in a thinking, knowledgeable society, it is a shared value.
Commercialization teaches us it is the equipment which provides the results. Buy this and you will be better simply by owning it.
Possibly, you've heard or read someone say a piece of equipment "looks good". "Looks good" and is efficient at its job are two vastly different things.
An education system not based on critical thinking doesn't value that distinction.
Therefore, while the op's video isn't necessarily wrong about anything it states, it preaches to the choir.
Those most in need of the critical thought process it promotes will not be interested in the actual thought processes required to make sense of the lessons being promoted. 
...and no, you do not get that cup of coffee!
