The new ugly
On the upside, Big Blue has released a significant range of varieties (sans, serif, monospace) and weights, but the range of symbols (Roman alphabet only) needs more work.
At first sight, it resembles other fonts from about 50 years ago, but the 'I' and 'J' glyphs are oddities. You can probably identify this font from the right angles in the bends of 'f', 'f', and 'l'. The line width varies where lines join. The slab serifs are too heavy.
