I like a little bit of rounding. Much like gaussian blur, the more subtle the effect, the more appealing it is (imo). Unfortunately, the design trend of over-the-top rounding has started to hit the mainstream and it scares me deeply. Microsoft has started baking-in rounded corners to their displays on Surface products (WHY?!), and MacOS now has more rounded corners than a Fischer-Price product.

It's a little ironic to me that we've literally resorted to "cutting corners" with our latest UX trends.
