Yeah no question, well written instructions (iFixit 💖) are better than even a well produced video, but I’d say the barrier to producing a useful video is much lower than to writing/photographing equally useful written instructions.
There are definitely cases where i vastly prefer video instructions to text though. Depends on what the instructions are about, the style of editing etc.
For example, seeing someone disassemble/assemble something is much more informative to me than a text that only vaguely describes where to find the next screw or clip, or that misses some important detail because the author thought it was obvious.
Don’t worry, he’s alright. I found him right beneath your comment:
