To be honest i have no doubt that companies do research with the best intentions but they also do it to get investment and some will be doing it knowing full well that that the real prize is to be bought out by a much larger company. A larger company that will almost immediately close down their operations and get rid of any competition that could potentially threaten its profits. This is not a far fetched idea i have dreamt up it is standard business practice especially with large pharma medical companies.
You’re overthinking it
Researchers don’t have anything close to a cure bcs they’re still on that mice f*****g stage. Maybe when we have flying cars they’d move onto experimenting on humans
