If I get the responsibility to promote someone, make sure to reread Chapter 31 of Peter Drucker's “Management Cases”. link: 버나드(@kms_bernard) 님의 트윗 많은 사람들이 간과하는 것 같은데, CTO는 회사의 경영자다. CTO가 하는 결정은 기술적인게 아니라 비즈니스적인것이어야 하고, 한편으로는 회사의 다른 비즈니스적인 결정에 기술적인 시야를 제공할 수 있어야한다. 그렇기에 내가 경계하는 것은 비즈니스적인 임팩트를 고려하지 않고 기술적으로 옳은 일을 하려고 하는 것과, 비즈니스가 기술적인 위험에 노출되도록 방치하는 것이다.

It is highly likely that your project is not suitable for writing Non GC Native language, so it is recommended to replace it with a VM-based language. I don't use C++ anymore for 99% of my projects.
