Inherent complexity does not go away if you close your eyes.
When you choose not to care about complexity, you're merely pushing it onto other developers in your org, ops people, your customers, someone. Now they have to work around your assumptions to make sure everything keeps running smoothly.
And nowadays, I'm often that someone, and I'm tired of it.
Because there is a lot to like in Go at first, because it's so easy to pick up, but so hard to move away from, and because the cost of choosing it in the first place reveals itself slowly over time, and compounds, only becoming unbearable when it's much too late, this is not a discussion we can afford to ignore as an industry.
Until we demand better of our tools, we are doomed to be woken up in the middle of the night, over and over again, because some nil value slipped in where it never should have.
It's the Billion Dollar Mistake all over again.

事件视界望远镜（Event Horizon Telescope, EHT）项目合作组织将于北京时间 5 月 12 日晚上 21 时举行新闻发布会。
本发布会将发布人马座 A* 的观测结果，这一黑洞位于银河系中心，发现结果将检验黑洞物理学的基础理论（比如测量事件视界的形状和大小），验证广义相对论在极端引力下是否正确。
