Minimalist design might look clean in portfolios, but I've found it often fails in real-world products where users need clear affordances. For instance, my banking app removed all visible buttons for a 'sleeker' look, and now older customers literally can't figure out how to transfer money. Good design should prioritize usability over visual purity, even if that means adding a few extra pixels of clutter. How much aesthetic simplicity is acceptable when it starts to hurt the user experience?
