Hello
@nnjoo :
The way you have phrased your OP, it is unclear if you are talking about yourself or some you are trying to help.
Until you state otherwise, I will presume that we are discussing your own situation and I will address you that way.

I know degrees have expiry dates and after a certain period of time your education becomes useless.
Since you are new to this engineering field (whatever it is), I suggest you stop worrying about "expiry dates" until more senior engineers pick up more information on your situation and tell you to worry about it - and I'm not predicting that will happen.
With regard to your "education becoming useless", in the engineering fields I am familiar with, that doesn't happen - new stuff just piles on. For example, having spoken to EE professors on these forums, the college curriculum is designed for adaptation to the workforce - where you will likely specialize. Certainly as a Software Engineer, it is rare for me to complete a workday without learning something new.

And if so what jobs are you able to get with a useless engineering degree if one has zero skills and zero aptitude in anything.
This is probably the biggest tipoff that you are talking about yourself. Who else would describe you that way? You need to convince me that your engineering degree is useless. There's such a thing as a "Chocolate Engineer", but if you were willing to relocate, I'll bet you could still land a job. As far as "zero skills and zero aptitude", I hoping you aren't putting that at the top of you resume. Convince me you have zero skills and zero aptitude.
In later posts, I will be asking about what you have done for your job search. But first we need to figure out what you should be searching for.
