I fear people who fear artificial intelligence

The crux of the article is that we have no clue what AGI will actually be like, therefore it is irrational to try and reason about it. I don't buy this, but even more importantly, the initial premise is wrong. We do have good reasons to believe an AGI's intelligence will be at least passingly similar to our own:

1. One path to AGI is straight up simulating a human brain in software.

2. Humans are guiding AGI research; even if we don't know how we'll build it, we always build things incrementally based on whatever available knowledge we already have. However, we ourselves are the only high level intelligence we have to compare against. Therefore, it's likely we'll build AGI inherently aiming to make it similar to ourselves.

3. The author subscribes to the runaway intelligence singularity idea to make the case that once we have an AGI, it will likely be near-instantly at least 1000x smarter than us, and thus incomprehensibly by us. That strikes me as unlikely; it is more likely that the first AGI will be built in some lab where it is already maximally utilizing the computing resources it is being run on, and will take at least a reasonable amount of time to gain enough knowledge and control of the outside world to begin its exponential self improvement.

I was disappointed with the author's reason for this fear; his idea is too simplistic and I don't think correct: "In imagining the motivations of this amplified intelligence, we naturally imagine ourselves." -- he's worried that those who think the robots will kill us are simply projecting that that's what they would do if equipped with superior intelligence. But that's just a silly conclusion; fear of the unknown is a far more common and obvious explanation to the frequent reaction to some AI superintelligence.
