We have limitations?

Hello guys
last week I saw an article with this title "Limitations of human brain mean we may never understand the secrets of universe, says Britain's top scientist", I was surprised how this can be possible, we have limitations but our equipments do not have limitations and also we are able to add extra memory, processor's and so on to our brains who said we can't.
I hope this guy with this nice smile have answers for these issues.

Do you agree with me?
