The physiologic and molecular changes associated with becoming older raise a person's odds of being sick and dying. Researchers can find ways to lessen the prevalence and severity of diseases by measuring and estimating the biological markers of aging. To distinguish between a person's biological age and their chronological age, scientists have devised "aging clocks" that use biomarkers like blood proteins or DNA methylation to estimate a person's biological age. These aging clocks can estimate the risk of developing an age-related illness. However, due to the need for a blood sample, other methods of locating equivalent measurements may make aging data more accessible.

Atrickle of AI-fueled misinformation has turned into a powerful stream over the past year, with fake photos and videos--from Donald Trump's and Vladimir Putin's « arrest » to the Pope's « gangsta » outfit--highlighting the scope of the problem. These types of creations come in a variety of visual, audial, and textual forms and can feature something innocuous, such as Jim Carrey in The Shining, or far more sinister and dangerous--like the fake videos of Joe Biden's « address to the nation, » for example.

Artificial intelligence in some shape or form has been a part of everyday life for years, but the meteoric rise of ChatGPT and the resulting aggressive development pace of conversational and generative AI models is, for the first time ever, putting the underlying technology into the hands of the general public. Even though current large language models are primarily able to guess the best-fitting next word in a sentence based on the corpus of content they were fed, CEOs, researchers and AI experts are now urging the industry to pump the brakes on training and developing models more capable than OpenAI's GPT-4. The company's latest large language model is currently available in a limited capacity for ChatGPT Plus subscribers and will soon be integrated into Microsoft productivity and security products. According to an open letter signed by influential figures like Elon Musk and Stability AI CEO Emad Mostaque, « powerful AI systems should be developed only once we are confident that their effects will be positive and their risks will be manageable. The Musk Foundation is a primary donor to the organization.

The United States is no stranger to technological arms races, having spent much of the Cold War in a two-pronged one-upmanship effort against the Soviet Union to build bigger rockets and land those on the moon. Its rivalry now is with China, and the latest battleground is artificial intelligence. China has long sought to dominate the AI landscape, laying out a plan to become a "global leader" in the sector by 2030 and pledging billions of state dollars for research and development. U.S. breakthroughs have been more organic, illustrated most recently by the rapid global uptake of chatbots made by American companies, such as Google, Microsoft, and OpenAI, with Chinese counterparts largely playing catch-up. One fundamental distinction is the private sector's role at the forefront of developing new AI capabilities: There were no private-built rockets in the 1960s.

When I was a freelance writer and historical-research assistant, I spent a lot of my time scrolling through microfiche in libraries. My journey into prompt engineering began in the summer of 2021, when I met a guy at a jazz bar who, at the time, worked for Copy.ai, which makes an AI tool that can generate copy for blogs, sales emails, and social-media posts. He mentioned that Copy.ai -- run on OpenAI's GPT-3 language model -- was having some trouble with the quality of its outputs and asked if I wanted to take a stab at being a prompt person. I didn't like the stress of freelancing -- plus, it seemed fascinating -- so I said yes, even though I was an English major and had no background in tech.

As 2023 progresses, demand for AI-powered devices continues growing, driving new opportunities and challenges for businesses and developers. Technology advancements will make it possible to run more AI models on edge devices, delivering real-time results without cloud reliance. Edge AI technology has proven its value and we can expect to see further widespread adoption in 2023 and beyond. Companies will continue to invest in edge AI to improve their operations, enhance products (i.e., safer, additional features) and gain competitive advantages. AI's adoption will also be driven by innovative applications such as ChatGPT, generative AI models (e.g., avatars) and other state-of-the art AI models that will be used for applications in medtech, industrial safety and security.

Artificial Intelligence (AI) is no longer just a buzzword in the tech industry. Today, AI is making its way into various fields, including art. AI is transforming the way artists create, present, and distribute their work. From music to visual arts, AI is being used in innovative ways to create new experiences for both artists and audiences. One of the most significant ways AI is changing art is through the creation of new forms of art.

Meme-makers and misinformation peddlers are embracing artificial intelligence tools to create convincing fake videos on the cheap. It wouldn't be completely out of character for Joe Rogan, the comedian turned podcaster, to endorse a "libido-boosting" coffee brand for men. But when a video circulating on TikTok recently showed Mr. Rogan and his guest, Andrew Huberman, hawking the coffee, some eagle-eyed viewers were shocked -- including Dr. Huberman. "Yep that's fake," Dr. Huberman wrote on Twitter after seeing the ad, in which he appears to praise the coffee's testosterone-boosting potential, even though he never did. The ad was one of a growing number of fake videos on social media made with technology powered by artificial intelligence. Experts said Mr. Rogan's voice appeared to have been synthesized using A.I. tools that mimic celebrity voices.

WHAT IF YOUR inbox were jam-packed with AI-generated emails? You may already be on the receiving end of emails written by artificial intelligence, with the help of a human prompter. Austin Distel, a senior director of marketing at Jasper, is one of those humans. Austin smiles as he demonstrates Japer's knack for email composition. "These are tools in my tool belt that helped me perform faster, but also better," he says before sharing that he often uses generative AI to rewrite work emails so they sound like Jerry Seinfeld. Email is one the least authentic forms of communication.

The companies touting new chat-based artificial-intelligence systems are running a massive experiment--and we are the test subjects. In this experiment, Microsoft, OpenAI and others are rolling out on the internet an alien intelligence that no one really understands, which has been granted the ability to influence our assessment of what's true in the world.
