I have every confidence that not only will Go survive, it will thrive. Go has demonstrated tremendous momentum over the past two years in terms of popularity growth. At TIOBE, Go is now #18. At RedMonk, it’s #15. At IEEE Spectrum, it’s #10. At PYPL, it’s #18. At CodeEval, it’s #10. At HackerRank, Go is #11. Two years ago, the language was nowhere to be seen in these ranking indices.
I wouldn’t put too much faith in the StackOverflow survey. It’s a self-selecting poll that isn’t statistically valid. For one thing, their sample size is only 0.35% of the world’s total number of programmers. That’s a drop in the bucket.
And consider this: polls can be tragically wrong. Last year, ALL the political polls predicted that Donald Trump would lose the Presidential election. All of them.
So take the StackOverflow survey with a large grain of salt.
I need to correct you on the age of Python. Python 3 is indeed young, but Python in general is over 26 years old. It makes little sense to single out Python 3.
