Can anyone really afford to develop for Glass?

I see it this way: if today everyone on the internet started using Adblock, and I mean every single internet user, most companies would still have a website, because the money they would be losing to the competition would be much more than the cost of keeping their servers up - it would just be part of the cost of the business, just like paying for ads now.
So coming to glass, if your competitor has an app in what promises to be the next revolution on computing, can you really afford not having a presence into that market?
Next, we have to wonder where the "Google has to make money from advertising!!!" camp is in this argument, because they usually tend to be ones who like to point out "Apple charges developers $$$ for access to their ecosystem". What a culture conflict we have.
Wondering how the square pegs are rounding out these days.
I don't think sure Google will advertise on Glass in the way people predict. Maybe they'll do some kind of suggested-search stuff, but nothing like some random banner ad bouncing around in the corner of your eye.
I don't think that's that much of a problem either; instead you'll have free Glass apps that consume paid (or freemium) web services. There's still plenty of ways for developers to use Glass to make money, even if the glass app itself isn't a paid app.
