There is a slight conflict of interest where more money can be earned by wasting the information recipient’s time via advertising. Text offers less opportunity to do this.
Perhaps some amount of time wastage is necessary to incentivize the information providers to provide the information, but the pendulum can also swing too far.
That’s why I got good at getting through videos quickly and figuring out when or if they’re a waste of time.
There’s plenty of “research” videos that are just spewing crap that can be found on a wiki or a database somewhere else on the web; but see enough of them and you pick up on the pattern and cadence and quality they’re produced at quickly enough to just move on when you see it.
