Maybe. A bigger impact factor imo is the distance between the tech you're using and the center of mass of training data. Showcase site in NextJS with a CSS gradient hero banner and a news letter? AI will be amazing. But then again, so will many no-code solutions. The sweet spot is probably custom enough that you're just outside of Wordpress but within well-trained domains like web and its popular frameworks. If you venture outside the mainstream, quality degrades rapidly.

Yes and no. If you have a hammer that works 98% of times, you might wanna use it a lot or not at all, depending on the circumstances. IME the double checking misses the point for production code. Might as well write it myself. Iām sure YMMV a lot.
