What Is Weak AI?
Let me explain what weak artificial intelligence, or narrow AI, really is. It's a form of AI that's restricted to a specific or narrow domain. This type of AI simulates human thinking processes. It can help society by handling time-consuming jobs and examining data in ways that people sometimes miss. You should contrast this with strong AI, which is a hypothetical machine intelligence on par with human smarts.
Key Takeaways
- Weak artificial intelligence (AI)—also called narrow AI—is a type of artificial intelligence that is limited to a specific or narrow area.
- Weak AI can be contrasted to strong AI, a theoretical form of machine intelligence that is equal to human intelligence.
- Weak AI lacks human consciousness, although it may be able to simulate it at times.
Understanding Weak AI
Weak AI doesn't have human-like consciousness, even if it can fake it sometimes. Think about John Searle's Chinese room thought experiment as a classic example. In it, someone outside a room thinks they're having a Chinese conversation with a person inside, who's actually just following instructions on how to reply in Chinese.
The person inside seems to speak Chinese, but they don't understand a word without those instructions. They're just good at following rules, not at the language itself. They might look like they have strong AI—intelligence matching humans—but it's really just weak AI.
These narrow or weak AI systems lack general intelligence; they're specialized. An AI expert at giving driving directions from A to B probably can't play chess with you. Similarly, one that fakes speaking Chinese likely can't clean your floors.
Applications for Weak AI
Weak AI turns massive data sets into useful info by spotting patterns and predicting outcomes. You'll see it in Meta's newsfeed (that's the old Facebook), Amazon's purchase recommendations, and Apple's Siri that responds to your voice queries.
Another case is email spam filters; the system learns via algorithms which messages are junk and shunts them to your spam folder.
Limitations of Weak AI
Beyond its narrow scope, weak AI can cause problems if it fails. Imagine a self-driving car that misjudges an oncoming vehicle's position and triggers a fatal crash. Or worse, if someone with bad intentions uses it—like a terrorist deploying explosives via an autonomous car in a busy spot.
There's also the issue of job displacement from automating more tasks. Will unemployment surge, or will new economic roles emerge for people? While the idea of mass job loss is alarming, AI proponents argue that as AI spreads, unpredictable new jobs will appear to fill the gaps.
