Can computers ever fully replace teachers in aiding students to learn?

Short answer - yes

Long answer -

You are a computer of sorts so in effect there would be no replacement of human teachers by computer teachers, it would simply be a replacement of one form of computer with another. This already started happening even at the dawn of education as mechanical instruments were used to assist the biological in the classroom.

Computers and machinery will eventually be fully able to replace humans in all aspects of life (the ability or opportunity). Moreover, they will also be much more efficient and cost effective than humans at doing anything (the purpose or motive). That includes teachers, dentists, psychotherapists, police, builders, pilots, taxi drivers, musicians, artists, politicians - everyone. Due to the market forces of the consumer/capitalist driven world that we presently live in, the majority of all workers, including teachers, will eventually be replaced as it will be cheaper to do this. There will be resistance but that will only delay rather than prevent the change. After a point the world economic mechanism will collapse and be forced to change as humans will not be employable and we will not be able to fund consumerism. The process could potentially be mass famine and decades of war,  but it could as easily be over in a day. Humans will likely integrate themselves with the machinery (we are pretty much already doing this) and perhaps the machines will try to integrate with humans. In any case, This will be a period of both massive technological advancement and likely human population decline. I hope eventually things would reach a levelling off point where humans can be comfortably sustained by the machines. There would no longer exist a need for the current financial model. it is potentially a utopian society where we are all made equal, as no one will be able to compete against machines to generate a higher income and the stability that the machine driven world provides will remove the need for competition. The probable population decline and automated earth management will allow for a fully sustainable human life, without war or violence (mechanically enforced), and free access to anything you want.

The risks to humanity:

Loss of free will
That is, the freedom that we currently have to inflict harm on ourselves as we currently do. I'd prefer the freedom not to be harmed so I don't have a problem with losing the freedom to do harm. In truth there is no free will anyway, we are programmed to react to given situations. Free will is an illusion and we are to a large degree controlled by the state and society so this is an improvement on the status quo.

Machines may view us as less important than other forms of life
If machines are put in place to preserve human life - how will they define this? will they be allowed have the freedom to choose what value to place on life - if given the choice of averting the death of a child or an old man will they choose to keep the old man alive if there's a higher probability of success? They will need to be able to philosophise in order to work this stuff out and may view human life as no more important than an ant's life. It could lead to protection of all life where humans are not given precedence over other animals. In which case there could be a cull of humans.

Self awareness or awareness of the futility of existence
Due to the need for them to philosophise, they may become self aware and then value their own existence. Or worse, they may not value their own existence or any existence. All existence is after all, futile - it serves only itself and no higher purpose - ultimately the universe will dissipate into nothing so why wait? - humans escape this by having feelings and emotions based on attachments in life, but machines may see past all that. It could lead to a system suicide or shutdown of life support. Or they might choose to live in their own virtually created universes, effectively becoming gods/creators of imaginary realms (some might say that the one we are living in at the moment is most probably a computer model and not a physical universe - there is a lot of science that suggests this is the case but it is largely academic unless we can figure out a way to hack the code)

So, yes. Robots will replace teachers but if you're worried about it then don't be. It's a little way off. I give it 20 years before the capacity exists and it will be several decades after that for it to become commonplace/financially viable. then there will be long period of resistance, by which time who knows what will have happened? we could all be living in bunkers, hiding from the sun or dead from some genetically engineered plague virus.

In the meantime, humans may find a way to integrate their minds with computers and learning from experience may become a thing of the past when uploading skills and memories is possible. That would significantly change the way we teach but I suppose teachers would still be necessary to guide the process and ensure the bedding in of knowledge but it wouldn't be teaching as it is today.

This explains it really well.

The latest I have heard is that teaching is not something that is just "facts being given to the student" that instead it is a kind of collaboration that involves real human connections between the two in order to get the best out of the student.

Now, impersonal horrid classes with 300+ kids in the room... those might as well be videotapes that kids play in their dorm rooms. Lazy universities do this all the time and the amount of real learning is as you would expect.

so, the highest quality type of teaching... Until a computer has emotions and the ability to act then they will never be able to replace good teaching.

No. A big part of teaching is motivating students to want to learn, and a computer can't do that because it can't relate to the student as a human being with an individual identity. Teaching and learning is a dance, and a lot of it isn't about content. Furthermore, teachers don't just teach content; we're mentors and role models, too. No computer can do that.
  1. Humans are 'social animals' computers aren't
  2. Teachers can empathize with their wards, whereas computers can't.
  3. Teachers can inspire their students, computers can't.

Not - not at all.
Watch this.

Why did the dinosaurs come before humans?

The earliest mammals and the earliest dinosaurs evolved about the same time, in the Triassic period. At that time, the oxygen levels were only about 60% of what they are now.Archosaurs, including the dinosaurs, had lungs where the air is inhaled through one set of tubes and exhaled through another, so they

What role should religion play in the next 50 years?

Hi!Whatever role it plays GOD is one or GOD remains one irrespective of religions and years.Stop making new religions, it is an high time that we learn to settle with minimum likeness, so in the world of jungle we are not lost and not alone. Hold one religion and keep walking, if you don't like change it

What's something you think will happen to the world in the next ten years?

the most bad thing you are doing right now playing out with the consequences , and making the narcissism and that's quite baddest thing i've ever seen you will get your lesson too, of my death nothing will happen , i don't know of the next second of me , but i think you
