I read the article (gasp! Shocking, I know) and recognise there are certainly important use cases for texting 911. But I work in EMS on a volunteer basis and I would think that in most cases voice calls would work far better, especially in medical situations. There can be a lot of helpful information that can be transferred in a more timely manner that way. Symptoms, time of onset, if situation changes during time of response, number of patients. Working in a rural area it can also be challenging to get an accurate location. In some situations, the 911 operators will also guide the caller in providing early care, such as CPR in a cardiac patient. So yeah, if one is physically able, and it's safe to do, take the time to talk to 911. They know what questions to ask and they will pass that information to the responding agencies so they know what to expect on arrival. Doing the same thing by text would only slow things down.
