Starfleet's fears when not knowing the cause would inhibit innovation. They'll sideline any tech not safe enough.
It's not that big of a stretch to me if you realize it's a trauma response.
Centuries go by without any alternatives?Come on. Thats incompetent. Even roddenberry figured there would be a replacement tech for warp drive. He nearly did it for tng only 80 years after kirk. 800 years going by with nothing isnt realistic at all. We developed eniac in 1945. By the early 80s desktop computers. By the early 90s laptops. 2007 smartphone. By 2022 a.i. All in less than 80 years. A simple calculator has more computing power than eniac now. Its ridiculous that starfleet can't get out of dilithium and warp drive.
