The term "artificial intelligence", or AI, often makes people envision humanoid robots. For some of us, this prompts concerns about their ability to outsmart us. The notion of robots passing tests that blur the line between human and machine, often depicted in science fiction, adds to these worries, particularly when considering the potential for AI systems to act in self-interest and make decisions independently.

## Specific and General Intelligence

Currently, no AI system can perform all the intellectual tasks that a human can. This is an active area of research, specifically into what's called **artificial general intelligence**. We aren't there yet. Currently, artificial intelligence systems are optimized to perform a specific task well, but not for general, multi-purpose tasks. For example, the AI application for recognizing voices can not be directly applied to drive cars, and vice versa. Similarly, a language translation app could not recognize images, and vice versa.

## Shifting Goalposts

Defining what AI is can be tricky because what experts consider to be AI changes frequently. John McCarthy, one of the leading early figures in AI once said, "As soon as it works, no one calls it artificial intelligence anymore".

For instance, 20 years ago, the idea of an email spam checker was new. People were surprised that an algorithm could identify junk email accurately, and called it “artificial intelligence”. Since this type of algorithm has become so common, it is no longer called "artificial intelligence". This transition happened because we no longer think it is surprising that computers can filter spam messages. Because it is not learning something new and surprising, it is no longer considered intelligent.

We often look at human intelligence the same way. For example, many years ago, only a few people knew how to use the internet. These people might have been considered extremely talented and intelligent. Now, the massive growth of online resources and social media mean that fluent internet use is almost required!

1. **Interface**: AI needs a physical interface or software for the trained algorithm to receive a data input and execute the human-like task in the real world. For example, you might interface with a chatbot in your web browser.

As an example, consider Amazon Echo’s voice control device [@wikiECHO]. The data set consists of customer voices talking to Amazon Echo or other devices. The algorithm predicts what a new customer voice is asking it to do. Given human voice request, it may set a kitchen timer. Lastly, the interface, is a physical device with a microphone, speaker, and computer software running the algorithm and accessing the data. It is the part that will interact with humans.

Like calculators, computers follow set procedures for problem solving and computation. Everyday computers use these procedures to help automate repetitive tasks and save time. However, this isn't generally considered AI, because the computer's algorithms aren't being trained with new data you supply. AI systems exhibit the ability to adapt and handle new inputs for tasks that might be more complicated.

Tanning beds are another common source of ultraviolet radiation. For melanomas and basal-cell cancers, exposure during childhood is particularly harmful. For squamous-cell skin cancers, total exposure, irrespective of when it occurs, is more important. Between 20% and 30% of melanomas develop from moles.[6] People with lighter skin are at higher risk as are those with poor immune function such as from medications or HIV/AIDS.

### Diffusion Models

Like transformers, diffusion models are useful for generative AI, particularly image generation. The key to diffusion models is that they have a lot of training in how to fill in the blanks. The model starts with many "noisy" images (imagine a photo with lots of holes or black spots) and tries to reproduce the original image. This process is called "denoising score matching". It then uses this training to generate entirely new content.
