Totally! I actually found it really surprising how boring the potential usage examples in the video were compared to what's possible with some of these ideas.
The jarring switch from "show amazing new tech with countless possibilities" to "you can train your child how to eat cereal!" made me question whether the whole video was really a clever parody.
Of course people are thinking about games right now. The first implementation I thought of was to reproduce the "hand seal/hand wave" spellcasting in traditional fantasy lore - and thus introduce a new genre of fighting video games: sorcery duels, also known as "Certamen" among Ars Magica fans.
