Pitchbook shows it as "Out of Business" since 2019.

They spent way too long procrastinating, with zero silicon after decades of work.

For comparison, RISC-V started years later and had a tapeout within a year and working silicon available as a commercial product in seven years.

2003: Mill computing started

2010: RISC-V project started

2011: RISC-V first tapeout

2017: RISC-V production chips available in the market

2019: Mill computing dead?
