请帮我分析一个英语句子

Question

If you give up studies while holding a job,you will in a couple of years have had yourself replaced by younger people.
这句话后面为什么是“have had...”呢？
请帮我分析下 这是虚拟语气吗？感觉是，但我又解释不清“have had...”做什么成分？先谢谢了

Answer 1

telecom才对吧。
But
it
does
mean
recognizing
how
important
they
can
be
building
the
energy
and
telecom
infrastructures
needed
to
take
full
advantage
of
the
Internet.
可以看作
But
it
does
mean
recognizing
how
important
they
can
be
needed
to
take
full
advantage
of
the
Internet,
when building
the
energy
and
telecom
infrastructures.
但它意味着认识到当建设能源和电信基础设施的时候充分利用因特网是多么的重要。

Answer 2

将来完成时
指“你不知不觉的发现自己已经被更年轻的一代给取代了”，作者希望表达这种已经完成的意义，因此用了have had

Answer 3

have yourself replaced让自己被取代
然后它加了个完成式
