Setting aside everything except the stated intention behind the author's post -- ie. to make right something that he could only conclude was wrong after a little education -- what if agentic dev was removed from the equation and he made a similar app anyway?

I understand that using agentic led to specific glitchy things like the recreation of an exact same bug arising from the exact same code which may -- very likely, actually, in cases where one of a narrow set of best practices (or dogma) are (blindly) followed -- or may not happen if you're building similar apps. A lot of people have a lot of the same ideas and the few from that set who actually pursue their goal will likely end up with similar products built with and operate using fairly similar patterns. What then?

What if it's an improvement on the original? Like a vast improvement?

Does a Pepsi or Burger King tell Coca Cola or McDonalds "You got it dawg ...", disrobe, hand over all their assets and find some place to die alone?
