sustaining technology versus disruptive technologies
Not at least any time soon.The future tech will be totally based on the foundation of bitcoin so you can never say it would replace bitcoin.Robotics can potentially affect bitcoin in many was.They can replace miners completely.
Quantum computing could iirc make cryptography, including ECC weaker (a 4096 bit key would be as easy to break as a 2048 bit key is now). However, if we could get people to agree on it, we could change Bitcoin to use a newer, quantum resistant system.
Yes that would drastically change computing in general and not just bitcoin.Same goes for high bandwidth connections which would transfer terabytes of data over seas in milliseconds.
