They fund a lot of R&D in house and let people try crazy new ideas. Too bad it's just for a niche product. They have a famous networking (optical and wireline) group doing a lot of state-of-the-art research, and they deploy these in their mainframe products. There's no other company like it. They are, in a sense, exact opposite of Apple where all HW engineers are pushed for impossible deadlines and solutions that save the day. Most in house developed IP is then not competitive enough and at the end doesn't end up in production (like their generations of 5G modems and the IPs in these like data converters etc).
