I have met Emma Haruka Iwao in 2019.
She was one of the main speakers at the Singularity Festival, in Heraklion, Crete.
An amazing person! I remember talking to Emma about her achievement. Emma then calculated the then world record for the most accurate value of pi which included 31.4 trillion digits, surpassing the previous record of 22 trillion, and entered the Guinness World Record.
Last weekend I watched this video where they talk about the 100 trillionth digit of pi.
