How do we build organisations that want to build safe AI?

11 min. read Submitted 01/05/2021 #writing #ai #question

Much has been written about the dangers of artificial intelligence, and how the intelligent systems we build may sometimes unintentionally drift in alignment from their original goals. However, we seem to focus almost entirely upon an Artificial Intelligence System (AIS) drifting from an organisation's values, and yet little attention is paid to the danger of an organisation's values drifting from alignment with the common good. It is our responsibility when judging risk to plan for bad actors, despite any desire to be optimistic about the human condition. We do not yet know if truly malevolent artificial intelligences will come to exist. We can be confident in the existence of such human beings.

This essay does not address the technical question of how you embed ethics within an artificial system, as much of the field focuses on. It instead attempts to draw attention to a more social question: how do we build organisations that are strongly incentivized to create safe and ethical intelligent systems in the first place?

Semantic Neurons

An idea I've been having a lot of fun playing around with is this idea of little generative algorithms to build mapping functions. When we normally think about a neuron within a deep neural network, we think about this point within a hyperdimensional space. The dimensionality of this space is defined by the number of neurons in the next layer, and the position within that space is defined by the values of those weights and biases.

If we think about what this neuron is actually doing, it is forming a mapping between an input and an output. We store this mapping naively as a very large vector of weights. When we want to see what the weight is, we just look up its index within that big vector. But imagine if you were a young coding student, and you were given the task to write a function that maps some input to some expected output. For instance, mapping an input to it's square. Would you really implement your function like:

On 'Some Moral and Technical Consequences of Automation'

In 1960, Norbert Wiener - widely considered the originator of the concept of cybernetics - published a short essay entitled "Some Moral and Technical Consequences of Automation". Here's the article that got me there, which is mostly about social media and an abstracted reapplication of these concepts, but they tie in the article a bit.

I find myself facing a public which has formed its attitude toward the machine on the basis of an imperfect understanding of the structure and mode of operation of modern machines.

Why Computers Probably Will Make Themselves Smarter

Recently, author Ted Chiang wrote an article entitled Why Computers Won’t Make Themselves Smarter. In this article, Chiang argues that concerns around a self-iterating Artificial General Intelligence (AGI) emerging as a superintelligence are unfounded.

We fear and yearn for “the singularity.” But it will probably never come.

Is a Self-Iterating AGI Vulnerable to Thompson-style Trojans?

In his 1984 lecture "Reflections on Trusting Trust", Ken Thompson (of Unix fame) speculated about a methodology for inserting an undetectable trojan horse within the C compiler binary that would self-propagate throughout all future versions. (Additional good video that got me thinking about this.)

The replacement code would miscompile the login command so that it would accept either the intended encrypted password or a particular known password. Thus if this code were installed in binary and the binary were used to compile the login command, I could log into that system as any user.
