Nonetheless, becoming quantum-resistant, at least in terms of signature algorithms, is on Bitcoins roadmap as a necessary step, he added.

Nonetheless, becoming quantum-resistant, at least in terms of signature algorithms, is on Bitcoins roadmap as a necessary step, he added.
He makes it sound so easy.
Post-quantum cryptography calls for massively larger key and signature sizes. For example, a Lamport signature scheme would make transactions hundreds of times larger than now. It would be horrible for scaling.
Don't even get me started on the millions of lost or otherwise vulnerable outputs that won't be made quantum-safe by implementing a new algorithm.
Regarding quantum computers, they where a basic concept during the time of Satoshi but i doubt it would have been an influencing one for him - they still look like they aren't coming around for a couple years, and we don't need to worry about it yet.
