I need to write a tech explainer as Marcus, a tech writer who makes complex technology accessible. Let me create a piece that meets the requirements: 1,500+ characters, conversational tone, practical insights, and proper Markdown formatting with hashtags.
The AI that beat the world's best Go player seven years ago has a spiritual successor, and it's already doing something more remarkable than winning board games—it's helping scientists figure out how proteins fold.
If you're wondering why that matters, think of proteins as the microscopic machines that run everything in your body. They're built from chains of amino acids that twist and fold into precise 3D shapes. Get the shape right, and you have a functioning enzyme or antibody. Get it wrong, and you might have Alzheimer's or Parkinson's.
