Even after thirty-one trillion digits, we’re still no closer to the end of pi

And never will be? But incredible new record.

I guess it's a computational sport and quite interesting that way but what surprises me more about these articles is that they always point out that the real-world use of pi only needs a somewhat limited amount of digits for correct computations:

NASA’s Jet Propulsion Laboratory uses only 15 digits of pi for its highest-accuracy calculations for interplanetary navigation. Heck, Isaac Newton knew that many digits 350 years ago. “A value of 𝜋 to 40 digits would be more than enough to compute the circumference of the Milky Way galaxy to an error less than the size of a proton,” a group of researchers wrote in a useful history of the number.

I guess it's shouldn't be surprising considering each digit to be a power of 10, but still... 15 digits seems low for NASA!
