a mere trifle
1.小意思,你别小看我,我在老家就常开船。
I used to drive ship in my hometown. Trust me!
2.小意思,克劳德先生。 而且别担心,我不收你车费。
Not a problem Mr. Cloud, and don't worry about the fee.
3.对则旅于一个超人智能来说,如果治疗人类所有疾病都不过是小意思,那么与奇点一同到来的自然该有长生孙派凳不老的羡差承诺——只要它发生的时候你还在世。
If curing all human ills will be a piece of cake for a superhuman intelligence, then the singularity carries with it the promise of immortality - as long as you're still alive when it happens.
