If you've been following me for a while you know that:
1) I'm a loud advocate of good UX above everything else.
2) I'm not a fan of the "design systems".
Why (2)? Because largely I believe it failed to deliver (1). From my experience Design Systems are an awesome drop-in solution for 99% of *anyone's* cases if and only if:
a) You take the design system as-is and are willing to bend your design choices so it does not violate said design system.
b) You don't develop your own design system (this would directly violate (a)).
c) Everyone in the team understands the interactions and intentions of every piece perfectly.
Sadly pretty much every company violates any or all of the above.
