I think Quantum Computing is overhyped nonsense just as Artificial Intelligence is.
For example, many companies use AI for customer for example Amazon, Google, Microsoft, all use AI for customer service chat and phone support.
I have probably used these AI bots hundreds of times for various customer service issues over the phone or through chat and I can't remember a single time they were able to actually answer a single question and solve my problem no matter how simple it was. Whereas a human would have resolved it in within seconds or minutes. AI voice and chat bots are completely useless but every company forces you to engage with one before they let you talk to a real person.
100% of the time the AI voice or chatbot ended up directing me to a real person because it said it couldn't understand my question that any 12 year old human would have understood. The biggest tech companies in the world even can't create a simple customer service AI bot that is remotely useful how do you expect them to do anything that is more demanding.
That's because they aren't AI in a way people usually connect the term with. Even best "AI" chatbots out there, like chatgpt are just combining are language prediction programs with a pattern recognition. They don't understand what you say, they just predict patterns. In a way they mimic what normal conversation should look like.
Road to actual "intelligent", learning or self aware AI, is far away and has all sorts of roadblocks that we haven't even started to tackle yet. Even though AI and quantum computing are in no way comparable, quantum computing computing is actually way closer to any practical solution then "intelligent" AI. Because quantum computing has already solved major problems. AI tech is basically just mimicking people, it haven't done any real break troughs when it comes to understanding what humans are talking about.
But quantum computers is in really early stage, and could take ages before it becomes a huge issue. But it will be earlier then any "self aware" AI, that's for sure.
