I consider this impossible in light of past decisions, such as Excel’s inability to handle elements of the human genome properly. This forced the scientific community to change the names of these elements due to Microsoft’s refusal to fix an obvious Excel bug. In other words, because of Microsoft, all of us citizens of the world have been affected by the change of the names of some elements of our genome, with all that this entails for scientific research and, consequently, for the treatment of genetic diseases.

The fault there lies with scientists who refuse to "git gud" & not use shit software.
