That is something I was just thinking about a few moments ago. I've haven't watched any of Hector latest stuff if he is still streaming. But between Hector, Alyssa, and Asahi Lina, they all 3 are pretty motivated and pretty excited to share. Which is great and something I wish we had more of. It helps to demystify these systems some. For many, GPUs and graphics APIs are just black boxes of magic and it can be hard to get past that. But content like this helps to remove the black box and make it more approachable.
I don't really care. Whoever is Asahi Lina, if they wish to be seen as a third, separate, content creator, that is how I see it. Could careless, just happy that someone is out there passionate and good enough to make it.
I only say this, because on a live stream from awhile back, I saw hector's username in the command line terminal that was being screenshared, implying Asahi Lina could be simply an alt for Hector. Just an amusing sidebar note.
