Do expensive tech events actually provide tangible value for your career, or are they just a waste of time?

Purely for the knowledge transfer, the investment is almost never worth it. Most talks and slides end up online for free anyway. The real value lies in the so-called "hallway track"—the spontaneous conversations between sessions, networking with like-minded peers, and the candid exchange about real-world IT problems, far removed from marketing buzzwords.

If you want to fairly assess the ROI of a conference, don't measure it in terms of "new knowledge," but rather in relationships and opportunities. A single honest conversation with someone who has already solved the same problem can save weeks of independent research. Set one or two concrete goals before the event—such as meeting three people in your field or discussing a technical question with practitioners. You can catch up on the talks via recordings later; the serendipitous encounters and hallway conversations only happen live.
