They say you can never go home again. Well, Pika somewhat disagrees.

Pika’s new “Selfie With Your Younger Self” feature transforms the popular social media trend into an interactive visual experience, allowing users to create videos where they interact with their past selves. This AI-powered tool taps into the deeply human desire for self-reflection while showcasing how generative AI can create meaningful personal content beyond typical AI image and video applications.

How it works: Pika’s tool merges a current video of a user with a photo from their past (or generates one) to create a video featuring both versions interacting together.

  • Users record a video of themselves in the present, then upload a photograph from an earlier period in their life.
  • If users don’t have access to an old photo, the AI can generate a childhood image based on the user’s current appearance.
  • Free users may wait up to an hour for video generation, while Pro subscribers receive their videos in under a minute.

Notable participants: Several internet meme celebrities have demonstrated the feature by creating videos with their younger, meme-famous selves.

  • Participants include Sammy Griner (“Success Kid”), ZoĆ« Roth (“Disaster Girl”), Kyle Craven (“Bad Luck Brian”), and Tay Zonday (“Chocolate Rain”).
  • These collaborations highlight the nostalgic and culturally relevant applications of the technology.

Best practices: The feature works optimally with specific filming and photo techniques.

  • Photos should feature only the person, as additional objects may confuse the AI (as happened when the author’s childhood photo with a doll resulted in a video with the doll instead of her younger self).
  • Users should leave space in the frame for the AI-generated image to appear, preventing their younger selves from being cut off.
  • Looking in the expected direction of where the younger self will appear improves the realism of the interaction.

Broader applications: The tool extends beyond simple nostalgia to offer meaningful ways for users to explore personal narratives.

  • Some users utilize the feature to document personal transformation over time, highlighting changes in appearance or style.
  • The technology enables multi-generational storytelling that honors family heritage and identity.

Future developments: With over 12 million users, Pika continues expanding its creative AI offerings.

  • Pika recently introduced “Pikadditions,” a video-to-video model that allows users to incorporate any person or object into existing videos.
  • These tools represent Pika’s commitment to enabling creative expression and personal storytelling through AI technology.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment

The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
