Actual access to reliable healthcare is a massive assumption to make, not everyone has incredible health insurance or lives in a country with sufficient doctors/med staff. Most places are in crisis for lack of resources, I'd rather ask chatgpt or Gemini for something urgent rather than wait 5+ hours in ER for the doctor to say "just take some aspirin and go to a walk-in tomorrow"
Not to mention, going to an ER for something that doesn't turn out to be an emergency carries a high risk of coming back home with something significantly worse.
Last time I was in ER, I accompanied my wife; we got bounced due to lack of appropriate doctor on site, she ended up getting help in another hospital, and I came back home with severe case of COVID-19.
Related: every pediatrician I've been to with my kids during the flu season says the same thing: if you can't get an appointment in a local clinic, stay home; avoid hospitals unless the kid develops life-threatening symptoms, as visiting such places carry high risk of the kid catching something even worse (usually RSV).
