This is really beginning to bug me now.

Punctuation marks are not followed by a punctuation mark!

Notice the lack of a full stop/period there? Well that's because it is not necessary as the exclamation point indicated the end of a sentence.

If you've been a hardware engineer for over 25 years, that would lead me to believe that you are at least 41 years old.
It really surprises me that a middle aged (sorry if this is wrong, it is an estimation) man, who clearly speaks English fairly well does not know/adhere to common punctuation practices. Something even non-native English speakers seem to comprehend.

This is not an attack, merely an observation and statement of the fact.
