I don't agree with the article either.
My view is that every company has its own DNA and that the web presence has to put this DNA in code. By DNA, I mean USP or niche. This USP or niche is tantamount to a trade secret but there doesn't even have to be innovation. Maybe there is just an excellent supplier arrangement going on behind the scenes, however, for projects, I look for more than that. I want an innovation that, because I understand the problem space and the code platform, I can see and implement.
A beginner level version of this, a simple job application form. On the backend I put the details from the browser session into form data. Therefore, HR could quickly filter out those applying for a local job that lived in a foreign country. They found this to be really useful. Furthermore, since some of our products were for the Apple ecosystem, I could get the applicant's OS in the form too, plus how long they agonised over filling in the form. These signals were also helpful.
To implement this I could use lame Stack Overflow solutions. Anyone scraping the site or even applying had no means of finding out if this was going on. Note the 'innovation' was not in any formal specification, that was just me 'being different'. In theory, my clumsy code to reverse lookup the IP address could have broken the backend form, and, had it done so, I would have paid a price for going off-piste and adding in my own non-Easter Egg.
I would not say the above example was encoding company DNA, but you get the idea. How would this stack up compared to today's AI driven recruitment tools?
As a candidate I would prefer my solution. As the employer, I too would prefer my solution, but I am biased. AI might know everything and be awesome at everything, however, sometimes human problems require human solutions and humans working with other humans to get something done.
Would I vibe code the form? Definitely no! My form would use simple form elements and labels with no classes, div wrappers or other nonsense, to leverage CSS grid layout and CSS variables to make it look good on all devices. It took me a while to learn to do forms this way, with a fraction of the markup in a fraction of the time.
I had to 'be different' to master this and disregard everything that had ever been written on Stack Overflow regarding forms, page layout and user experience.
AI does not have the capability to do super-neat forms like mine because it can't think for itself, just cherry-pick Stack Overflow solutions.
I liken what you describe with running out of Stack Overflow solutions to hill walking ('hiking'). You start at the base of the trail with vast quantities of others that have just stepped out of the parking lot, ice cream cones in hand. Then you go a mile in and the crowd has thinned. Another mile on and the crowd has definitely thinned, big time. Then you are on the final approach to the summit and you haven't seen anyone for seemingly hours. Finally, at the summit, you might meet one or two others.
Stack Overflow and blog posts are like this, at some stage you have to put it away and only use the existing code base as a guide. Then, at another level, you find specifications, scientific papers and the like to guide you to the 'summit'. AI isn't going to help you in this territory and you know you haven't got hundreds of competitors able to rip off your innovation in an instant.
