Kdb/q is like minimalist footwear. But you can run longer and faster with it on. There's a tipping point where you just "get it". It's a fantastic language and platform.

The problem is very few people will pay 100k/month for shakti. I'm not saying people won't pay and it won't be a good business. But if you want widespread adoption you need to create and an ecosystem. Open sourcing it is a start. Creating libraries and packages comes after. The mongodb model is the right approach IMO
