As the different streams having their sources in different places all mingle their water in the sea, so, O Lord, the different paths which men take through different tendencies, various though they appear, crooked or straight, all lead to Thee.” Swami Vivekanand
As the wise men like Vivekanand expressed, there are many paths that men/women take to reach their destinations (be it search of God or Model Accuracy). And all of those who have learned data science and related streams will be able to relate with this, that these different paths start with different languages, different tools, and different expectations. During this long and arduous journey towards excellence, some start from SQL, and others learn Python. But as we all know by now, in long run knowing only one of these will not suffice.
