Your translation makes little sense and has grammatical errors. In order to understand what it might mean I asked "deepL" to translate from Chinese and it did a slightly better, but not great, job. Working from that translation, this is what I produced: "Why be humble when you comprehend what others might not? Competence entails responsibility. For everyone's benefit, let us stand aside and allow the most capable to exercise their abilities."

I agree with the others that the original translation is terrible and nearly impossible to understand. I'll try a translation myself. Why should I be modest if I understand things that others do not? It is irresponsible to humans to understand without doing it(okay, the previous sentence makes so little sense that I couldn't translate) . Modern society should let people with superior knowledge control the "arena" in which everyone else must live/operate.

No
