Very cool, congrats dude!

Well, first of all, the article is just a business promotion trying to sell some AB test. "Note: If you’d like to run AB tests like this to help increase your ecommerce site’s conversion rate, you can learn about working with us here."

Secondly, it's very obvious that the user would click more on something that they can actually see rather than something they don't, how they are supposed to click on a button that can't see.

Stick on mobile should be mandatory, generally speaking of course.

Just by looking and interacting with it, getting designer peers feedback (design review), performing heuristic analysis etc.

But sure, if you got the time and money, I'm sure Netflix has a lot of these, why not run an AB test–I'm not against AB tests or any other, any information is always valid even if it doesn't aggregate in the end. But in my opinion, A version is clearly a better version than B without having to run an AB test.

Just share your UI with Invision or XD, they are great for feedbacks. Just try to have only one tool for feedback, this will keep you from wasting time and getting insane, especially because all these departments feedback should also be aligned between each other as well.

Brutalist trend lives on.

I wouldn't need an AB test to know that version A is a better choice, just by the fact that A version is simpler and more objective, it makes me think less than version B before I can take any action.

But hey, some people just need to see metrics to believe.

The only difference between them is that Design is the expression and purpose of a Brand/Product/Service and Art is the expression and purpose of an artist.

But Art uses design like design uses art, so technically and methodology speaking they are the same, even though the line between them is blurry.

Apple or Google UI kits I use all the time. But design UI kit never. Don't really see the point since you're being paid to do exactly that, that's just being lazy or you don't have the skills, and looking from a client point of view, I wouldn't want to have a generic product or website.

"Show consolidated menu" and display hamburger menus as best practices for mobile is misleading, it's definitely not good user experience.

As a designer, you should never worry about being a specialist or generalist, your main concern should always be to thrive as creative as possible, that will make you succeed in the field.
