I shall describe the construction of a unital pre-C*-algebra A which is stably finite, in the sense that every left invertible square matrix over A is right invertible, while the C*-completion of A contains a non-unitary isometry, and so it is infinite.
The talk is based on a joint paper with Jared White, which will appear in Proc AMS.
