Competitors mentioned: Frink, Wolfram
Concerns raised: Unclear use cases and documentation, Inconsistent unit conversion (converts time but not storage units), Doesn't handle complex dimensional analysis
Feature requests: Reference previous results in new expressions, Support for exotic unit conversions (e.g., bananas to petabytes using Bekenstein bound), Use Frink as backend or similar dimensionally-aware computation engine
