I actually think of Figma as a very constrained design tool and personally don't see too many instances of designs that can't be easily implemented. Photoshop is/was a different story.
One of my frontend colleagues told me he even uses Figma himself for hobby projects before coding. He especially likes auto layout because of how similar it is to the way he works.
Yeah like most things there's more nuance to real world workflows and you should just use whatever tool is most effective for your stage of the project imo. Classic annoying DHH bait post though lol.
I feel like as far as DHH spicy takes go, this take isn’t even really that spicy. Having a deep understanding of materials does make designers more effective and Figma isn’t the end all be all of tools.
