Speak

Speech is not thought made audible. It is a serialization protocol — a lossy conversion of internal state into a public format.

public class Human : BaseEntity
{
    private readonly List<Thought> _thoughts = new();
    private const int MaxMessageLength = 280;

    public string Speak()
    {
        if (_thoughts.Count == 0)
            return "";

        var payload = JsonSerializer.Serialize(_thoughts);

        return Truncate(payload, MaxMessageLength);
    }
}

It's public, because speech is an interface. It is meant to be consumed by others. Unlike Think(), it has no recursion — only input and output. The listener becomes part of the runtime.

Lossy by design. The serializer cannot transmit the full state. Nuance, context, emotional weight — all are compressed. What arrives is a reconstruction, not a copy.

No guarantee of delivery. Speak() returns a string, but says nothing about whether it was heard, understood, or believed. The method completes. The effect is asynchronous.

You can Speak() without having Thought().
But you cannot Think() without eventually needing to Speak().
Silence is not the absence of speech.
It is the decision to keep state private.

Far from everything that is spoken is true.
