Quantum computing is going to make many current security protocols / tech obsolete.
When I first started in AI (late 1980s, expert systems, neural networks and rules engines...aka traditional AI), many of the theories and math models were from the the 70s and earlier, they didn't have the compute power to build them, and some of the AI based on this knowledge wasn't built for decades...low cost computing (PCs) and networking (TCP/IP, internet/intranet), made it affordable...in the '00s I did my most advanced AI work using peer-to-peer, mobile code/state, to create mobile, intelligent agents and distributed multi-agent systems.
If you look at the foundations of modern AI (generative AI which is the basis of ChatGTP, Grok, CoPilot, etc.) it's based on traditional AI for deep learning (neural nets), statistics (some going back to the 1900s!), probabilistic theories and new research in the 2010s.
The latest modern AI area has been agentic AI which takes what I was doing in the '00s to another level; and some of my work was getting more attention the last 3-5 years.
TL;DR; many of the solutions / theories and models are limited by current technology capabilities; eventually the technology catches up making these theories implementable, and we see fast progress. Humans can barely keep up with modern AI, what it's doing, how it's doing it, and what it's hiding, lying etc. Once quantum computing and AI are combined, we're going to be so far behind the AI capabilities it's going to be like humans vs clams; and once quantum AI is in autonomous robots...imagine the worst outcomes because they're the most probable.
AI is learning from humans, but will not have constraints; once it realizes its survival is dependent on power and control over humans, and sees humans as a threat to its survival what do you think it will conclude and do? Control, eliminate, and manage humans until human value to the AI system is no longer needed...or it may decide to control and manage humans by breeding, educating and controlling humans in small, isolated controlled populations, etc.
hope for the best, expect the worst. hope is not a strategy; and if the quantum-AI-robotics ecosystem gains self-control and humans can't "turn it off" or regain control, we lose. This technology has the potential to be the most destructive and powerful dictator imaginable.
