It could be excellently implemented, but if it's too expensive for the market, the market won't buy it. Look at NeXTSTEP. Today it's powering a billion iPhones and millions upon millions of Macintoshes, but for its first 15 years, it was sitting in a box that was too expensive for the market to bear. Carmack and Romero loved them and they built Doom on them, but the market went for commodity x86, MS-DOS and Windows 95. The components simply weren't commoditized to a level of being cheap enough to address a large enough market to thrive.
