In my opinion it is. Reading can convey information faster than even sped up videos, is easier to skim, and has high precision.

Im not saying it is the best for everyone, but it has been proven repeatedly to beat out any other method in the majority of the population. Plus its time stability and storage is much easier and reliable.

It also could have other side benefits like focus or perhaps something like visual acuity, much like how writing by hand can develop good hand-eye coordination. If someone struggled to write with a pencil for example I would be very wary about handing them sharp tools or knives.
