Yes, and you can really tell who gives a shit based on what they do with their subtitles. Both Clint from LGR And Alec from Technology Connections do their own real subtitles and it shows. Not only are they actually correct, which the auto generated ones usually are not (typically around proper nouns but they get all kinds of homonyms wrong all the time, too) but they also sometimes add asides or in-jokes which only appear in the captions or deliberately describe the racket some gadget is making in a particularly amusing way.
