The implication is rough, but it is part of the truth (not all of the truth). However, I will add that the anointed ‘high-end’, your lifelong long backend devs, devops, data engineers, etc are adding to the problem. Backend people taking up the frontend hat under the fullstack guise create tons of awful end results, and this is even more common because they already exist at the company and are given a blanket ‘competent’ rating (in other words, they get a chance to mess with the curve before anyone else).
All of this is part of the pervasive problem that your post is slightly tainted by (my attitudes are tainted by it as well), which is a general disrespect for frontend. No matter, the truth of these attitudes will show up in all of our products. It’s always obvious to me which teams take frontend seriously and which don’t (the quality is always literally visible).
