Despite a flood of Sunday morning hype, it’s questionable whether computers crossed an artificial intelligence threshold last weekend. However, the news about a chatbot with the personality of a 13-year-old Ukrainian boy passing the Turing test did get us thinking: Is tricking every third human in a text exchange really the best way to measure computer intelligence?

Computers are already smart, just in their own ways. They catalogue the breadth of human knowledge, find meaning in mushroom clouds of data, and fly spacecraft to other worlds. And they’re getting better. Below are four domains of computing where the machines are rising.

Information retrieval
Given the right set of rules, computers are the ultimate librarians. Google’s search algorithm shakes down 50 billion web pages every time you need to prove your boyfriend wrong about his latest baseless assertion. It’s so good at its job that many people consider clicking to the second page of search results an act of desperation.

Where it’s headed:

Understanding human language is one of the most difficult things computers can do. Beyond basic subject/verb agreement, decades of bots have mostly failed at figuring out the vagaries of the written word. Unlike us, computers struggle to understand how a word can change meaning depending on its neighbors, says Russ Altman, a biomedical informatics researcher at Stanford.

Solving this problem is Altman’s obsession. Since 2000, he and his colleagues have been teaching a machine how to get meaning from some of the densest language on the planet: medical journalese. The Pharmacogenomics Knowledge Base (PharmaGKB) has read 26 million scientific abstracts to create a searchable index of different effects that various drugs have on individual genes. The program understands things like clauses and how the meaning of a word can be modified by the words around it (which is important for parsing dense phrasing that might send a confusing message about whether a drug activates a gene), and also knows many synonyms and antonyms. The resulting database is hugely important to pharmaceutical companies, who use it to save time and money on basic research when they are searching for new drug combinations.

Robotics
Robots that work in controlled environments, like car manufacturing plant, are impressive enough. But getting them to do programmed tasks alongside humans, who have complex behaviors, is one of the most difficult challenges in computing.

The vanguard of intelligent robotics are droids that let humans do tasks that require creative thought or fine manipulation, and fill in the organization and heavy lifting where needed. For example, Amazon already has armies of organizational droids that shuttle items for packing from a Manhattan-like grid of shelving towers to human packers.

Where it’s headed:

Researchers are getting better at teaching robots how to read the syntax of human movement, so they can work more closely on more complicated projects. David Bourne, a roboticist at Carnegie-Mellon University’s Robotics Institute, says the key is to play to both the human and robot strengths. “A person is actually more dextrous, but a robot can move to an exact position really well.” Bourne made a robotic arm that assists automobile welders. In a trial, the human-robot team assembled a Hummer frame. The robot had a video projector that showed the human exactly where to put different parts and then made perfect, 5-second welds. For more difficult welds, it deferred to its partner. “Together they were able to do the project 10 times faster than a team of three human professionals,” says Bourne..
