I’ve yet to see a technological solution that doesn’t fall victim to this.

I’m a reasonably intelligent software engineer and I would not trust myself to audit the described solution to know it does what it claims.

I can, however,

* review the receipt produced by the voting machine and ensure it matches * observe the random audits of submitted receipts to tabulated votes to be sure they match

I can also trust that a wide section of the public can do those things as well.
