Adam Back suggested that the emergence of quantum computing could force Satoshi Nakamoto to move their Bitcoin to protect it, revealing whether they are alive.[...]
During an interview after a Q&A session at the “Satoshi Spritz” event in Turin on April 18, Back suggested that quantum computing may force Nakamoto to move their Bitcoin. That’s because, according to Back, Bitcoin holders will be forced to move their assets to newer, quantum-resistant signature-based addresses.
Back said that current quantum computers do not pose a credible threat to Bitcoin’s cryptography but will likely threaten it in the future. Back estimated that quantum computers may evolve to that extent in “maybe 20 years.”[...]
Consequently, he suggested that Bitcoin should be prepared to switch to quantum-resistant signatures but only do so when necessary. He suggested a Bitcoin taproot-based implementation allowing addresses to switch to quantum-resistant signatures when needed.https://cointelegraph.com/news/quantum-computers-likely-to-reveal-if-satoshi-is-alive-adam-back Dang so in 2045, that's true long term thinking right there. I do imagine at some point in the future Satoshi had to have hid some Easter egg or something like a message to be found but only time will tell
