The screen sharing one has bitten me a couple of times. I record live classes for students, and we've had occasions when someone who was away goes back to the video and it's a black screen with me nattering away as if they can see it :/
That said, apart from the shitty embedding support and their channel management, I REALLY like Stream and using it for a video lesson platform. The captioning is quite good even for my fast talking, Aussie accent and jargon.
Ah yes, I noticed the live CC recently! I tried it out in a conf call between myself (very Scottish accent), a Swede, a Norwegian, an Indian and an American - it really was amazingly accurate for everyone!
That said, beyond novelty I'm not sure how useful a CC feature is.
Some of my students tell me I talk too fast, so it can be helpful for them to review content, and I've had quite a few students with varying degrees of hearing impairment. Pretty useful in my field.
