If 90% of the code I run is in safe rust (including the part that's new and written by me, therefore most likely to introduce bugs) and 10% is in C or unsafe rust, are you saying that has no value?
Il meglio è l'inimico del bene. Le mieux est l'ennemi du bien. Perfect is the enemy of good.
That is an unexpected interpretation. Use the best tool for the job, also factoring what you (and your org) are comfortable with.
