Good. I'm not into it personally but I don't begrudge people who are, however women who aren't already emotionally invested in the idea buying ASMR gear on a whim have virtually always wasted their money. They do it once or twice and then their overpriced mannequin head is lost under the bed, never to be seen again. Even if you did name an example of it being a good use of their money, it then becomes a shift in content that brings with it a commensurate shift in audience; who wants their vtuber to change if they're already emotionally invested? No upsides for the established audience.
