With the advancements we've seen in technology over the past 20 or so years, how long will it be before we replace ourselves with artificial intelligence?

It's not happening anytime soon. We might be able to get some parts of our lives automated and smarter but true replication of the human brain would require some form of advanced quantum computing.

We don't think in terms of 1s and 0s

"I have found that the reason a lot of people are interested in artificial intelligence is the same reason a lot of people are interested in artificial limbs: they are missing one" - David Parnas

But think about it: out daily lives are already so filled with AI, and our lives will only continue to be filled more and more with AI assistance.

@xroad sums up my thoughts quite good. Unless we are able to develop small quantum based computing machines (like smart phone size) and back lots of them together we won't be able to mimic a human brain. The thought process is just too complicated to break it down into linear programs.

@SirWindfield true that. But just like early computing even a supercomputer the size of a room with human-level intelligence is probably not something we'll see in our lives. Unless we discover something new that's as revolutionary as the transistor

Augmenting ourselves and improving our lives in many ways is already happening. One area is health. People with physical and mental challenges are able to walk, see, hear and communicate as a result of software and adaptable devices. This will be greatly enhanced in the next few years. Specialized suits already allow people with some forms of paralysis to walk. Just imagine what that does for a person.

True AI will happen. Probably sooner than we think. We already have the computing power to map lower level species. Quantum computing and 100x software will provide the tools for human AI within 20 years. Thoughts?

@Jumpshot44 we can make people see again, we can make them listen again, we can cure diseases that weren't meant to be cured once. Seeing how far computing evolved from the very beginning (10-15t weight for a 'home computer') I would guess that the step to true ai isn't far away. Siri is a good example of what we are able to do today. A digital assistant that analyzes our habits and provides context specific information.

A real AI, something that can think as complex as we can do, might be nearer then we think.
If we develop real AI that can communicate with language (as we use now) and is able to learn new ones like we do, programming is a matter of time. Within less then a year the AI would be able to code as we do (just my assumption). Code is (in the syntax) not more than a language. Each construct (block) is like a sentence.

And we might even be able to "teach" them the true nature of computers, machine code.
Next comment contains more information about something that Iread

So I recently read in an article about research being done on the architecture of computers. The same architecture has been around for 30 years. It is quite outdated. It works, but it is in its basics old. Scientists have started to think about a new way to create computers and not having the normal RAM, CPU, Gpu, MB constellation. Quite hard to think about another way but I am open for new ideas and technology.

The think is, if we develop QC (quantum computing) that can be used in today's sense (there is already QC being around, but it cannot do much for normal consumers) the whole old architecture might not work out for us. We need to change it to make it efficient to use.
Just my idea on this ^^
