I don't mind video or audio if i _know_ i want it. But it's obscenely slow to verify if video/audio content is worth my time.
So much content on the internet is shallow or misleading. Text is easier to filter for me.
Spoken like a true luddite! XD
For me, this is pretty contextual. Sometimes I want to listen to audio when I'm on a walk or doing dishes. Other times I want text so I can skip the audio and save time. The more mediums, the better, personally speaking.
Isn't there a variety of text-to-speech apps available?
Yes. I turn CC on for most videos, even movies or shows watched at home.
Why not? Not everyone is in a room by themselves and can turn up the volume. Not everyone can wear big gamer headphones at work.
Posting a video on the internet and not including a transcript is like posting something on Instagram and no other platform and thinking, "That's good enough."
If your goal is to communicate your thoughts, you make them available to as many people as is practical.
You don't publish a book and slip it onto one shelf at one local library and then wonder why nobody reads your work.
If Google's billions can't solve the problem, Rando Startup is going to have to be awful clever.
