...Why does every explanation how to do something have to be a video now?...

Well, it's a bit of a digression, but I think I can answer your question.
I didn't know that what you refer to was the case until fairly recently, when a tech support guy in a PC hardware supplier shop told me that, if I wanted to find the
latest workaround for a certain product (a TP-Link USB Wifi dongle), to get it working under Windows 10, then I should search YouTube, and NOT the discussion forums.
When I asked why that was, he said that it was easier/quicker to produce a short YouTube video than it is to document a solution.
Anyway, I followed his suggestion, and discovered that he was only about half right, and eventually I found a fix via a forum discussion that led to a new hardware flash update for the dongle, and new drivers.
Recalling the advice to search YouTube, I looked in YouTube for other fixes and workarounds for other problems, and I was surprised at the number of vids there were for supporting this and that, but most of them were mediocre.
My theory as to why this is is that a large number of people probably find it easier to make an amateur video on YouTube, and probably get more satisfaction from viewing their video and hearing their own voice, than there are people able to enjoy
documenting a solution and seeing it in writing - because of relatively low levels of literacy.
Similarly, a large number of people probably find it easier to, and thus prefer to, watch a video - because of relatively low levels of literacy.
I generally find watching a video for information to be a slow and tedious exercise, so I only do it as a last resort, if I can't find it documented somewhere.
Having said that, I do think that training videos - e.g., demonstrations showing how to use a piece of software - can be tremendously useful and often succeed in being the simplest/fastest way of communicating something, but the presenter has to be trained and skilled in communication and making presentations - and self-aware - for this approach to be successful.
Only today I saw a classic example of how
NOT to do it, on a Microsoft website offering Office 2016 training videos - I was looking for something for my 15 y/o daughter to use for Excel training.
In this video (sorry, I didn't keep a link to it), the presenter was a young Asian-looking woman who sounded like a native English speaker. She spoke in what sounded like clear English, but with a very slight twang - possibly Aussie or Kiwi.
Unfortunately, even though she possessed a nice voice, her elocution was very poor. Not only did she speak too rapidly (maybe nervous, I don't know), so that she kept clipping some of her words, making them hard to decipher, but also she started sounding her vocal fry register about halfway through each sentence and continuing it to the end, and sometimes tailing the tone of her voice upwards at the end of the sentence, thus contorting a statement into a question.
So I rapidly switched off the video and hunted around for one presented by a better communicator, for my daughter.
The unconsciously-made vocal fry and the upwards tone would have to be two of the most annoyingly bad, distracting and
avoidable bad speech habits a person can have - they are typically habits of immature girls with poor language skills, though I did once hear a young man unconsciously performing the upwards-tailing tone at the end of
every single sentence. These bad habits can be learned by girls at school as a form of unconscious protective colouration to gain acceptance by a group, and can often be accompanied by excessive use of redundant words including "like" and the phrase "you know". They can be crippling habits, in terms of career development.
