In the past, he has also worked on languages for embedded reconfigurable processors and on algorithms for accelerating the rendering of complex 3D scenes.

Burkhard Kloss

I only came to England to walk the Pennine Way… 25 years later I still haven’t done it. I did, though, get round to starting an AI company (spectacularly unsuccessful), joining another startup long before it was cool, learning C++, and spending a lot of time on trading floors building systems for complex derivatives. Sometimes hands on, sometimes managing people. Somewhere along the way I realised you can do cool stuff quickly in Python, and I’ve never lost my fascination with making machines smarter.
