Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
