Sebastian Esposito, 9, from Albuquerque has written in 10 languages and 12 fonts, and his TikTok videos have surpassed 20 million views.
He was diagnosed with autism at age three and displays hyperlexia, reading far beyond his peers. By two he could read 200 words, a milestone noted by his parents.
The boy memorizes the periodic table, recreates logos of Disney and Ray‑Ban, names the capitals of all 50 U.S. states, and identifies national flags by shape alone.
His TikTok handle, @little.einstein, now boasts half a million followers, and the channel serves as a platform for raising awareness about hyperlexia, a condition he and his family share.
Although his speech remains limited, writing has become his voice. His parents, Ryan and Amanda Esposito, provide markers, chalk, and puzzles, and he keeps posting to spread knowledge and support others with similar challenges.
