You should read up more on growth mindsets. People and technology aren’t fixed. They change and improve over time.
If people had your attitude about AIDS we would have let all AIDS patients die because “oh well nothing we can do.”
Luckily those with growth mindsets and optimism didn’t listen to people like you and now AIDS patients take a single pill a day.
The same could happen with cancer to, but not if people like you are in charge.
