Interesting slides: Peter Gutmann - Why Quantum Cryptanalysis is Bollocks
Since quantum computers are far outside my expertise, I didn't realize how far-fetched it currently is to factor large numbers with quantum computers. I already knew it's not near-future stuff for practical attacks on e.g. real-world RSA keys, but I didn't know it's still that theoretical. (Although of course I lack the knowledge to assess whether that presentation is correct in its claims.)
But also, while reading it, I kept thinking how many of the broader points it makes also apply to the AI hype... (for example, the unfounded belief that game-changing breakthroughs will happen soon).
