“Evolution”
“Evolution” Wesley’s experiment to improve the performance of nanites gets out of control when they develop a consciousness and the ability to reproduce themselves. They occupy the ship’s computer and cause multiple malfunctions. The scientist Dr. Paul Stubbs who is observing a stellar phenomenon feels that his research is endangered, and he begins to destroy the nanites, whereupon the nanites sabotage life support on the ship. When Stubbs apologizes, the nanites help to repair the computer and are transferred to a planet in the Kavis Alpha system. summary by Ex-Astris-Scientia
Wesley messed up! Wow! And he wasn’t the one to save the ship and crew. This alone would make the episode worth watching!
What was even more fascinating for me was seeing the nanites on a big screen and see how they’re developing a culture of their own. And Data, being able to communicate with them. Yeah. As many times before and after, it’s a pity we don’t get to see the nanites ever again.
