The comment you replied to was not questioning the value of integrated cabling. It was pointing out that the product description on the site does not make sense.
"Cloud computer" sounds like a server you rent from AWS. It's kind of like calling Rust "cloud compiler."
If you choose to use words that your audience doesn't understand, or even worse understands to mean the opposite of what you want them to mean, it's a good idea to explain these words immediately using conventional words with conventional meaning. The comments by throw0101a did that.
The product seems really cool, but there is no way I would've understood what it was from the website.
And for what it's worth, I don't think you need to explain what's happening to Steve, it seems to me that he understands perfectly well. To me you come across as being rather condescending and in my opinion Steve is being commendably polite in response.
Cloud as a term is pretty undefined/overloaded. It makes sense to me if I think about 'cloud' computing as API-based provisioning on pooled resources.
