There are at least three types of AI:
1. Artificial Narrow Intelligence (ANI) is an AI created for one specific task (for example, defeating a world chess champion)
2. Artificial General Intelligence (AGI) is an AI capable of performing many tasks (comparable to human capabilities)
3. Artificial Superintelligence (ASI) is an AI capable of performing many tasks at the highest level (exceeding human capabilities)
When we talk about Google's RankBrain, and other machine learning algorithms that currently work at Google, we are obviously talking about ANI.
Similarly, RankBrain Google, ANI are those spam filters in our mail, my favorite Google Translate and IBM's Watson, and the Amazon feature that recommends us buying, and unmanned vehicles.

Inside ANI, there are a lot of different approaches. Pedro Domingos, in his book The High Algorithm, divided all scientists involved in the problem of improving AI into several groups:
- Symbolists
- communicators (Connectionists)
- Evolutionaries
- Baesians
- analyzers (Analogizers)
RankBrain made in the camp of communicators. They believe that all our knowledge is encoded in the connections of the neurons of our brain.
RankBrain's particular strategy is that experts call the back-propagation method of the error, and after rebranding they began to call “deep learning”
Communicators claim this strategy is able to learn everything from raw data, and, ultimately, automate the search for new knowledge. Google, apparently, also believes: On January 26, 2014, Google announced the acquisition of DeepMind Technologies, which was essentially based on the backpropagation method.
Summarizing, we can say that RankBrain is an artificial intelligence created for a narrow task based on the “depth learning” technology. Having dealt with this, let's see how far they have come and, more importantly, how will this change the SEO business?
The exponential growth of technology (and AI)
We tend to underestimate the future - all because in our assessments we wrestle with past historical experience. However, the reality is that progress accelerates over time. Ray Kurzweil calls this the Law of faster returns. The scientific rationale for his theory is that more developed societies have the opportunity to progress more rapidly than less developed ones because they are more advanced. Of course, the same conclusions can be applied to the field of artificial intelligence.
Here is a visualization of the Law of faster returns:

As you can see, and indeed feel intuitively, the improvement of the methods of deep processing and computers follows from the Law of faster returns. Here is another shocking revelation: at some point, the processor power will surpass not only one person, but all the people together.

In fact, it now seems that we can create multitasking artificial intelligence (AGI) by 2025. Technologies are clearly growing at a rapid pace, and, according to many testimonies, most of us will be caught off guard.
Superinteller Growth
As I explained above, RankBrain is just one of the forms of ANI, which means that it can perform tasks better than humans in one particular area, which means it is a relatively weak form of artificial intelligence.
But soon we may be stunned by how quickly this “weak” artificial intelligence can easily turn into something with which we have no idea how to deal.

Here you can clearly see that Google's RankBrain, being super smart in one particular task, is still in the general context of things, rather weak in the general sense of intelligence.
But what happens when we apply the same Law of faster return to the field of artificial intelligence? Here are the conclusions of such a thought experiment by Tim Urban:
“... So, watching the development of AI, we will soon see how easy it is for him to become smarter than an animal. Then, when he reaches the minimum level of human intelligence - let's say a 'village idiot' - we will exclaim: “Oh wow, this is so silly. Pretty little. ” Only here the range of lacking intelligence between the fool and Einstein is not that great - so very soon after the “fool” we will hear about the creation of AGI, which is even smarter than Einstein “.
