Compilation time: It is not rare to see Modern C++ applications taking 10 minutes to compile. With traditional C++, this number is counted in low seconds for a simple change. Maintainability: you want simplicity. You need simplicity. The Real Reason: But the real motivation why I do not spend much time with Modern C++ anymore, despite being pretty good at it at some point, is just that there is much more being developed in the industry that needs my attention. Conclusion: One has to learn C/C++ but cannot find the language in itself be sufficient. 每一位個體都有自己學習的能力及習慣，在使用這些工具程式語言時，也是相同的道理，端看自己的對於這種語言的學習成熟度與熟悉度，主要還是要看你本身要使用它來解決什麼問題？這些問題的背後是否已經有人提供很好的 Library 來支援？自己從頭到尾來打造輪子、自造汽車，那似乎也未免太過於辛苦了。 對於作者提到工業界的需求，在這個觀點上，可能 modern C++ 也許不是那麼重要，但...
