This is what I'm seeing in the design market. With Figma Make, you can write a prompt, tell it to use your design library, generate a flow, and then hand it off to developers and say "Hey, look at this, can you implement this?". Alternatively, you can use Cursor/Claude Code/Codex to pull in Figma design system elements via MCP, and generate flows that way. You can push features so much faster with the same or fewer people, and lets be honest, pushing more features in less time is the #1 metric at a lot of companies even if they claim otherwise.
I find it to be sometimes easier to utilize my Figma library to design what I want as I generally don't have to do rework. It gets annoying after awhile to waste tokens and context dealing with stupid small things like "Hey, the icon in the icon button is wrong." if you do prompting. Pulling in the same icon & icon button through a MCP is generally easier.
Presumably you can iterate on and manually tweak the design first, which is much quicker and less cumbersome than iterating on and tweaking the design when it's in clunky HTML/CSS/JS form and all the non-vector graphical assets are flattened/cropped etc.
