Why Google buying Twitch is a good deal for content creators and streamers

I've had this discussion with a few people earlier and we've came to this conclusion and thought. Imagine Twitch followers and Youtube Subscribers merging. Now imagine like over 2000 Youtube personalities with 500K+ streaming on Twitch with their whole subscriber base following. The growth rate would be even more astronomical than it is currently. Twitch streams will get a major boost in viewership due to this. This would make even more partners which would ultimately make Google even more rich with ads and subscriptions.
