I do agree that the dumbing down of universities comes from universities, and the prominence and political power of nonsensical areas of study drags everyone down.
I don't see much of a difference. The majority of engineers I've interacted with have actually been well adjusted people who can coherently think and write.
The time a CS graduate spends learning algorithms and honing fluency in computer languages is spent by a history major reading, analysis and writing papers. On average you tend to be better at things you do a lot. It’s not to say the average engineer cannot think and write, but those aren’t skills you select for. In some cases, you may need engineering talent who can not communicate in your language!
Engineers write less and for a different purpose. A technical writer, newspaper journalist and novelist approach a similar action (writing) with a different approach and methodology.
There’s a reason why you see attorneys in leadership roles outside of their domain than other professions that attract smart, diligent workers. (There are few doctors in politics or non-medical corporate leadership positions, for example.) They tend to be better at broad-scope analysis and zoom in a deeply technical area with consultative assistance, and they tend to be better able to communicate the outcome of that analysis. They tend to be humanities or social science majors.
In CS there was an emphasis on clarity, succinctness, and thinking about how well you've communicated your ideas to your intended audience.
Having said that, maybe the large volumes of writing practice from history made me receptive to those lessons.
There were also a couple of history professors who were very good at cutting through overly flowery and insufficiently meaningful writing with comments like "where is your evidence for this?".
However, I will say that the apprehension of works of beauty and the development of abstract thinking patterns with regards to ethics, anthropology, and metaphysics are valuable, for reasons I'm not certain how to articulate. I might only say that I would not wish to live in a world without them, and would consider anyone who--having the means to appreciate them and the requisite intellectual ability--found them simply unnecesary or undesirable, to simply lack som essential form of humanity.
