So, unsafe block every 70 LoC in 1500 LoC toy example? Sure, it's a strong argument.

How is that worse than everything being unsafe?

I've seen this argument thrown around often here in HN ("$IMPROVEMENT is still not perfect! So let's keep the statu quo.") and it baffles me.

C is not perfect and it still replaced ASM in 99% of its use cases.
