There is no overlap now.
Because quantum is extremely weak now, the end goal of quantum is to recreate how a brain works, could your brain do what AI does now?! Yes or no?!
Yes, our brains do what AI does better than AI right now. The only reason an AI model can do something better than an individual now is purely brute force with the underlying computational resource. The entire goal of AI is to emulate how a humans brain solves problems and currently the best AI, with few exceptions, cannot do that better than we can. There are three levels of AI; Artificial narrow intelligence, artificial general intelligence, and artificial super intelligence. Currently we are just barely getting closer to artificial general intelligence. Let me define the three for you:
1. Artificial narrow intelligence (ANI) - Capable of performing one niche task at a time under a single domain with specific context. Examples of this level include; image recognition, speech recognition, natural language models, or natural language processing, fall under artificial narrow intelligence.
2. Artificial general intelligence (AGI) - Capable of performing multiple tasks, as a human would at a humans level of ability, across multiple relevant domains. It would be capable of learning and adapting newfound knowledge across multiple domains. A couple examples of attempts to move towards AGI, but are clearly not there, include; OpenAI, Deepmind, and many others.
3. Artificial super intelligence (ASI) - This level surpasses humans' level of cognition and ability to learn and adapt across all domains simultaneously. This level would have developed emotions, beliefs, decision-making methodologies, information processing strategies, and beyond human levels of IQ. There are no examples of even progress towards such a level.
If you want to argue with the above, talk to
Mehak and Megha Kalsi, which is where I derived most of the above.
