Unless it's a technical question that we can't best answer for ourselves.
We can't understand everything or come to our own conclusions about every topic. If I want to know the best way to build a bridge, make a cake, draw up a contract, treat a fracture, or whatever else it is probably best to rely on expert advice. In principle I could study engineering, cooking, law, medicine and so on myself, to the best of my ability, and find the best possible answers myself. But at a certain point (very quickly in fact) it becomes far too much. We simply need to rely on expert opinion to exist in the modern world.
Some seem to regard philosophy as exempt from this principle. As if expertise doesn't or shouldn't carry the same authority in this area as it does in say engineering or law or academic subjects like physics or biology. That our opinion is as good as a philosophy professor. Dawkins seems to have this view of philosophy, which is quite odd when you think about it. He wouldn't accept that someone who hasn't studied biology has views on evolution that are as valid as his own. Yet he thinks that his own views on philosophy deserve a hearing. He can only do this by denigrating the entire discipline he is engaging with.
To make a long story short, I am perfectly open to the possibility that a philosopher or a computer scientist may have insights into the nature of reality that I am not able to grasp because I do not have their training. In principle I could scrutinise their reasoning down to the basics, but this would be a very lengthy undertaking and may require a lifetime of study. Truly understanding something is not the same as simply following an argument closely. Because understanding requires huge background knowledge of various subjects, not simply acquaintance with the grammar and select vocabulary or a topic.
I think it is reasonable to defer to a "smart" person. In fact it's a key skill to learn when to defer to the knowledge of others and working out who is expert and who is not. We all made the mistake of thinking JW leaders were experts on the Bible, life and everything. It doesn't mean that we shouldn't defer to anyone about such matters. It means we should be more discriminating about who we defer to.
