Stephen Hillenburg revealed that he has recently been diagnosed with ALS, a rare terminal illness that affects the central nervous system. He is apparently in the early stages of the illness, but will continue to work on SpongeBob for the time being.
It's heartbreaking to hear about this, but I wish Stephen the best while he deals with this.
