This shows a lack of understanding of neurobiology. 200.000 neurons don't "see"; they register and respond to the action potential generated. Adding more to that simply means you have more possibilities to respond. Having 10000 billion neurons does not automatically imply intelligence. To try to simplify it down to mere numbers, e. g. "this must be a worm", shows that there is a lack of understanding of the core tenets of neurobiology. This also includes non-action potential involved understanding, e. g. the special role of certain mRNA/proteins, re-recreating memory and so forth: https://pmc.ncbi.nlm.nih.gov/articles/PMC6650148/

But even aside from this, the whole premise is weird. Science always includes the scary parts. Nuclear energy can be used for peaceful production of energy and it can be used to obliterate people, as one country has shown to the rest of the world. You have a similar issue with regards to biology in general. You could also see this with drones - you can use drones to deliver goods via air to people, or you can use it to deliver an explosive payload to help in warfare. I don't fully understand the "I am scared" part. This is a general problem, not one limited to biological computing at all.
