Yes! The thing I love most about browsing without adblock is seeing endless ads for tech conferences about programming languages I don't know, on platforms I don't use, held on continents where I don't live. I especially love the culty business lingo they use for pitching these conferences at me. No I'm not "obsessed" with anything my job involves and I'm frankly worried for anyone who is.
Now see you've got it all wrong. This solves all your problems: Google knows what you do, where you live, and where you go, so they'll always show you ads for relevant conferences with the most reasonable adjusted prices.
