Commodities are fully fungible goods and services. Different implementations of a single algorithm should have the same basic formal properties, by definition.

Commodities are fully fungible goods and services. Different implementations of a single algorithm should have the same basic formal properties, by definition. That is, they should be roughly fungible. Else you aren't dealing with correct implementations of the same algorithm. If anything, the thesis "algorithms are now commodities" is less true now than ever before. As the complexity of software deliverables increases, the use of complex, proprietary algorithms in software should likely increase in turn.
