Redesigning Humanity: Evolution 2.0

Enriquez opened by noting how unprecedented our era is. For 99.9% of human history, life was predictable — the same animals, the same seasons, the same threats. Today, technologies reach 100 million users in months, and we carry capabilities in our pockets that would have each been considered the most valuable invention in all of history. Despite the daily barrage of alarming news, we are living in what he called "times of miracle and wonder," with dramatic declines in child mortality, violence, and poverty.

The heart of the talk asked a provocative question: if Darwin were alive today, would he write the same books? For four billion years, evolution was driven by natural selection and random mutation. But humans have been steering evolution for millennia — breeding wild mustard into broccoli, kale, and cauliflower, fermenting grapes into wine, culturing milk into cheese. What's changed is the speed and precision. The discovery of DNA's structure, recombinant DNA, and then CRISPR have compressed what once took hundreds of thousands of years into hours. Enriquez described helping build the world's first synthetic life form and the development of desktop DNA printers that can produce an mRNA vaccine from a pathogen's genetic sequence before it even reaches a population.

Enriquez then turned to what he sees as the next frontier: the brain. While we are increasingly able to regenerate organs and reprogram cells, the brain remains the bottleneck for longevity — not just because we can't yet regrow one, but because it carries the data that makes a person who they are. He highlighted the rapid emergence of neural interfaces and electroceuticals: the first FDA-approved at-home transcranial stimulator for depression, expected to be available in summer 2026, along with a growing wave of brain-computer interface research for epilepsy, pain, addiction, attention, and memory enhancement.

A live demonstration brought the point home. Ana Maiques, CEO of Neuroelectrics, joined from the audience to show her company's portable EEG and brain stimulation device. She shared that they are eight weeks from the readout of a Phase 3 FDA clinical trial using non-invasive brain stimulation for drug-resistant epilepsy in children — potentially the first such approval in history.

Enriquez raised pointed ethical questions about where this leads. Social media companies built an "attention economy" by making their platforms deliberately addictive. What happens when that becomes an "affection economy," with AI companions and neural devices that can modulate pleasure, attraction, and emotion? He described an upcoming convention of leaders he is helping organize to develop guidelines for emerging brain technologies before these capabilities outpace regulation.

Looking furthest into the future, Enriquez speculated about a world where intelligence might transition from a chemical to an electrical basis — brains modeled as patterns of electrical impulses rather than wet chemistry. Such a shift could make interstellar travel feasible, carrying human consciousness in compact silicon rather than fragile biological bodies requiring thousands of calories a day. It's highly speculative, he acknowledged, but a natural consequence of taking deliberate control over evolution.

In the Q&A, the conversation turned to AI and whether its intelligence will plateau or follow an exponential curve. Enriquez noted that AI systems are already writing their own code and beginning to experiment autonomously. Whether that trajectory leads to a superintelligence indifferent to humanity depends on which model of intelligence evolution proves correct — a question he called absolutely critical for the future. He also addressed the "genetic debt" of modern medicine: by shielding ourselves from natural selection, we've built a powerful protective bubble, and dismantling it — through vaccine refusal or the erosion of public health infrastructure — would be catastrophic.
