What if you could live forever, staying healthy and young for centuries? Scientists and tech pioneers now believe this dream could become reality. In Silicon Valley, entrepreneurs like Bryan Johnson follow intense routines, like his'Blueprint' plan, to slow or reverse aging, and companies like Altos Labs are testing treatments that have already extended the lives of mice. Experts say we're on the cusp of technologies that could make immortality possible, and they've even set dates for when this future might arrive. Three visionaries stand out in this quest: futurologist Dr. Ian Pearson, Google's Ray Kurzweil, and biomedical researcher Aubrey de Grey.

We are now in the later stages of the first generation of life extension, which involves applying the current class of pharmaceutical and nutritional knowledge to overcoming health challenges. In the 2020s we are starting the second phase of life extension, which is the merger of biotechnology with AI. The 2030s will usher in the third phase of life extension, which will be to use nanotechnology to overcome the limitations of our biological organs altogether. As we enter this phase, we'll greatly extend our lives, allowing people to far transcend the normal human limit of 120 years.

Amazon is rolling out a new beta feature that lets advertisers create AI-generated image backgrounds for products.

The company views the feature as an ideal alternative to product shots in front of generic white backgrounds (or bad Photoshop jobs). Amazon says the process is easy and requires no technical expertise.

'Mom?" repeated my daughter's voice on my phone. My heart sank and I started trembling. I heard a man instructing her to lie down and put her head back. My 15-year-old daughter, Briana, was at a skiing competition with my husband two hours away, and I instantly thought she'd been badly hurt. I was in my car, picking up her sister Aubrey, who is 13, from dance class in Arizona. Over the phone, I heard Briana bawling and shouting, "Help me, help me."
