Of course you think that, you don't have to rely solely on closed captions! It's usually not even posed as an expectation, but as a request to correct captions that don't make sense. Especially now that we have auto-captioning and tools that auto-correct the captions, running through and tweaking them to near-perfect accuracy is not an undue burden.

Yes, but most deaf people can't do that. Even if they can, they shouldn't have to.

There's helping people and there's infantilizing them. Being deaf doesn't mean you're stupid. They can figure it out.

Deleting thousands of hours of course material because you're worried they're not able to understand autogenerated captions just ensures everyone loses. Don't be so ridiculous.
