Step-by-step explanation:
According to "April 2026: The Long Years," Ray Bradbury is saying that loneliness can be experienced as a form of imprisonment, potentially dangerous and indicative of questionable motives in the eyes of others. This loneliness could even be taken as a sign that intelligent species may not survive in the grand scheme of the universe. The narrative suggests that isolation is an undesirable state that deviates from human social norms and can lead to despair and a sense of futility. This aligns with a broader theme in Bradbury's works where he explores the psychological impact of technology and futuristic scenarios on human relationships and our innate need for companionship.
