Now, not every modern building has to look like a glass and steel colorless brick.
For example, I really like the look of Oodi [0], Helsinki's new library: it reminds me of wood covered with snow, and the interior is exactly what you would expect from a modern building (built in 2018).
The article reads like the author picked a conclusion and made things fit his opinion.
In my experience, the biggest issue is natural light - it's hard to beat glass walls when you need a structural skin with some windows where possible.
