There is little doubt that AI will be a successful technology. Ultimately, it will be able to create computers that are a lot more aware of the context in which they are used and which are much better at processing large amounts of unstructured human-made information. Personally, I find that the talk about AGI mainly serves as a marketing pitch, as well as providing an excuse for trampling over existing regulations.

The second point is much more worrying. In the near future, the amount of plausibly-human content generated by machines will dwarf the actually-human content created by real people.

Right now, people reading this comment will assume by default that it has been written by a real person. It might not be long until that default assumption changes.
