Being able to compress well is closely related to acting intelligently, thus reducing the slippery concept of intelligence to hard file size numbers. In order to compress data, one has to find regularities in them, which is intrinsically difficult (many researchers live from analyzing data and finding compact models). The suggested open-ended Human Knowledge Compression Contest should spur the wider community to develop intelligent compressors, increase visibility and impact, and leverage funding, and accelerate progress in artificial intelligence.
