If instead the two where entirely not connected (ie it was impossible to choke on food) that would be a much more sensible design. The two connected pipes with the flap that blocks the food from going down the breathing hole is good enough, it isn't a good design.
You’re joking right? If the oesophagus was split into two pipes you’d need two mouths and two noses. If the tube to the lung just connected to the nose, then we would be unable to speak, because it is the action of the tongue and teeth which allow control of speech. Likewise if the tube to the stomach connected just to the mouth, we’d be unable to taste because the nose is pertinent in our ability to taste. If the tube just connected to the nose if it became blocked say during a cold, you’d suffocate. The problem of two tubes does not stop an allergic reactions because the type 1 sensitivity would cause the oesophagus regardless of connection the mouth to inflame. So two oesophagus would not solve this problem.
There are no issues with the system we have, the reason people choke is because they abuse that system: not chewing before swallowing, eating too quickly. Yet most humans swallow millions maybe billions of times across a life time, yet how many times do we choke in our life? For the sheer volume of humans, the sheer volume going through the throat and the sheer use of the system there are very few failures of that system, it has a lower rate of failure than than the most carefully constructed human system.
There are several issues with the system we have, and it could be much, much better.
We definitely wouldn't look anything like we do now, and we probably wouldn't have developed the same language as a result, but it would be an improvement nonetheless.
