Maybe some day, in the distant future, humanity will harness the advanced technology necessary to run two timers at the same time.
I hope I’m alive to see it.
Update (February 9, 2023): As reader Miraz J. notes, belying the “dumbwatch” label I’ve given it, the Apple Watch is capable of running two (or more!) timers at once. This feature was actually added in 2021’s WatchOS 8 release, which makes it even more comical that the vastly more powerful iPhone can’t do it in 2023.
