Once completing that trail, we will then reconnect to the towpath and head to the Potomac Overlook on Olmsted Island for some great views of the falls and cascading water. After reconnecting on the towpath for a short distance, we will connect to the Gold Mine loop trail in the forest and Gold Mine Overlook and return to our cars. There are a couple of short hills while in the forest but they are small, otherwise the route is mostly level. There are a few small stream crossings on Ford Mine trail that are easily crossed. We may include the River Trail which runs along the shore of the Potomac, depending on the water level conditions. **Participants will have the option to do as much of the hike as they desire.** The pace will be about 2.5 mph. **Bring**: Adequate water/hydration, snacks/lunch, and sturdy hiking shoes since there are some rocky areas and tree roots in the forest.

Very few books are absolute must-reads. This is one.”―Siddhartha Mukherjee, assistant professor of medicine at Columbia University and author of The Gene: An Intimate History "During the 25 years I have known Jamie Metzl, he has always been ahead of the curve. There is no one better to help us understand and prepare for the fast-approaching technological revolutions. Superconvergence is brilliant. I can't recommend it more strongly."―Sanjay Gupta MD, bestseller author, neurosurgeon, and Emmy-award winning chief medical correspondent (CNN) "Our world is defined by our science and technology—whether we like it or not. The question now is not whether to use these powers, but how best to use them. In Superconvergence, Jamie Metzl takes us on a journey through the new capabilities that are radically transforming ecosystems inside us and around us, challenging each of us to get personally involved with building the future we want."―Beth Shapiro, University of California Santa Cruz evolutionary biologist and author of Life as We Made It: How 50,000 Years of Human Innovation Refined―and Redefined―Nature "In a fine counter-blast to the pessimism of today, Jamie Metzl lays out just how spectacular the future of humanity and planet can be if we harness innovation responsibly and imaginatively to create what he calls the 'spiral of progress.'"―Matt Ridley, author of How Innovation Works, and co-author of Viral: The search for the Origin of Covid-19 “A page-turning journey through space and time that shows us how our lives will be changed by imminent technological advances we once only dreamed of.”―David Sinclair, Professor of Genetics, Harvard Medical School, and author of Lifespan: Why We Age―and Why We Don't Have To “The superconvergence of the genetics, biotechnology, and AI revolutions provides spectacular opportunities for building a better world. It also represents an almost limitless investment opportunity. We were excited to collaborate with Jamie Metzl, one of the world's great experts on how these aspirations can best be realized, including in capital markets. Superconvergence is a master class for imagining, investing in, and building a future we'd like to inhabit."―Jeremy Schwartz, Global Chief Investment Officer, WisdomTree “A clear examination of a transitional moment in the story of life on Earth…. Metzl capably describes recent developments in genetics and biotech and looks at how AI is providing an analytical engine of unprecedented power…. An important book in which the author sets out a path for the future based on his experience and expertise.”―Kirkus “Erudite, optimistic, and timely.”―Science Magazine "[In Superconvergence] Mr. Metzl has identified an important truth: that the convergence of new technologies is galvanizing us to reimagine how to meet urgent challenges in medicine and the environment. It’s a compelling opportunity—provided we manage to sidestep self-induced catastrophes along the way."―The Wall Street Journal ### About the Author Jamie Metzl is a leading technology and healthcare futurist and the founder and chair of OneShared.World. He is the author of Hacking Darwin: Genetic Engineering and the Future of Humanity and four other books and was a member of the World Health Organization expert advisory committee on human genome editing.
