I'm not sure inhalable is a feature. Insulin pumps/pods micro-dose fast acting insulin throughout the day to cover your basal dose, you can't do that with fast-acting insulin via inhaler. You can't close loop your inhaler with a CGM to adjust your basal based on your current BG and automatically control for overnight highs/lows. You can't dose your kid from across the room from your smartphone.

Also there seems to be a a notable incidence of lung cancer which raises a bit of a yellow flag there...
