Despite the remarkable diversity and a range of astonishing adaptations in these prehistoric insects, all of them ultimately went extinct. Environmental changes, competition, and glaciation patterns served as hindrances to their survival.

Unfortunately, under current conditions, it appears unlikely, but one can only imagine the fascination and awe that such a world would foster in those willing to explore it. Whether one would prefer to encounter these ancient giants or remain content in their modern, smaller forms remains a subjective choice in the landscape of evolution and Earth's history.
