Instead you try to discredit him and use Ad Hominums.
The term is "ad hominem", short for "argumentum ad hominem".
Ad hominem is fallacious reasoning, like "Laddy has black hair so he's wrong".
Calling Laddy unqualified is not ad hominem. It is relevant to the argument from authority he's trying to make.
Laddy's quotes were cut such that they say something different than the author intended as shown in the larger quote. That's also not ad hominem. I would probably just call it a fact.
Now, I don't really think Laddy found these quotes himself. But wherever he got them, he is not approaching this topic in a scientific manner.. I think Laddy lacks the background to genuinely discuss much of anything in natural science, including these quotes.
I know he works in programming, but I'm fairly sure he does not have a degree in CS. Honestly, I would assume Laddy has a humanities education.
