You don't necessarily have to stop coding. Various technologies such as voice recognition systems developed for users with disabilities exist and, with advancements in algorithms and the overabundance of processing power available on modern hardware, are much more capable than they were before. Businesses are also generally more receptive to accommodating employees with disabilities than they were in the past.

To address an uncomfortable point, yes, such systems are more awkward to use than typing and you may hate to have to use them and be unhappy to compare yourself against what you used to be able to do and what your peers remain able to do. I can only say, having a disability myself, that becoming disabled does indeed suck and that it may be of some small comfort to remember that everyone eventually becomes disabled by the progression of age.
