> feel like scam

More like people flock onto immature projects with large sum of money hoping for a quick 5x making the projects look far larger than they should be and when they fail to deliver, depression is as large as their investment leading to feel they got scammed.

I'm not saying cryptocurrencies aren't interesting, I'm just saying you're overstating their case relative to other technologies and the novelty (eg, that it even is novel, as opposed to normal engineering on top of ideas that have been around decades) in saying that it's underrepresented.

(Also, AI and bots are the same topic, but that's a tangent.)

I would argue we should hear about them less than automated truck driving specifically, based on potential economic impact and current spending levels.

(Which, actually, seems to be about the trend -- we see small bursts of a few stories a day when a major event happens, but otherwise, it's mostly just a low murmur among other things.)
