> without online media, computers would be in the sector of scientific instruments

Computers were already common household items before massive online advertising even existed.

So forgive me if I don't find your arguments convincing (and it's not just because of this specific argument).

So your assertion is that there would be no online media in the absence of behavioral advertising?

I rather suspect that's incorrect, for two reasons. We had plenty of online media before online advertising existed at all, and there are many ways of doing advertising without it being behavioral.

Not plenty and nowhere near as popular

I have an enjoyable and well-paying job in the sector of scientific instruments.
