And that's assuming, again, that technology doesn't improve. > No, you are trusting them to overwrite the encryption key and that the encryption being used is secure. 1. That's hardly any more reassuring (though at least it does hopefully mitigate overwriting concerns, assuming that key can't be recovered and the encryption method is indeed more secure) 2. That doesn't explain why secure erase commands take so long relative to other ATA commands (anywhere from seconds to hours), or why that time scales with drive size.
