Unfortunately, the expert in debugging Arduino electrical errors, or in numpy, or in evaluating what the burn pattern on your spark plugs means, or in identifying that strange object in your telescope, won't be on IRC. He'll be on Reddit, where you'll need a government-provided ID _and sanctioned device_ to participate. Or on Facebook, where you'll need a government-provided ID _and sanctioned device_ to participate. Or on whatever large, popular platform replaces them, where you'll need a government-provided ID _and sanctioned device_ to participate.

But rest assured, so long as you want to discuss privacy and nostalgia of the pre-invasionary internet, you'll find a knowledgeable expert on IRC.
