I mentally checked out by the time he mentioned buying ray bans as some radical personal statement on privacy and tech nostalgia.
Tech nostalgia is driven, in part, by a lack of excitement about what current companies are offering. It wasn't really present when we were all excited about Apple, etc.
That nostalgia signals there's a market for alternatives, which we've seen some companies serve, and expect others to enter. This will provide us with more choices apart from "Apple" vs. "Google" end-to-end ecosystems.
Tech is also fun because we have some new categories for the first time, perhaps since mobile. VR isn't popular per se, but I consider it mature. Ray Ban Metas are also a new category (consider an emerging AR application — or more of a glorified camera device, for now). A first person point of view for videos is very different than what's captured by a smartphone; I feel like I'm "there" when I watch travel videos I've taken with them, much more than when I watch what's taken with my phone.
The only personal statement I'm making is that tech seems primed to be fun again (though we probably have to anchor our expectations around a local maxima)
The worst thing about the internet is that it gave everyone a voice.
Engage with or amplify content you agree with. Create content of your own that represents your values or ideas. If you want, try to persuade others where you think they're wrong.
Overall, if you can feel good about what you've put out there, that's enough. You'll field comments like this no matter what it is.
You are entitled to your opinion, as I am to mine.
Exactly as you stated, if you cannot handle the criticism, do not go public.
