Here's a speculative scenario that doesn't seem so insane:
Albania has a roadmap for EU accession. The roadmap is broken up into discrete tasks. The tasks have estimates for time to completion. They've been able to quickly hack away at 5.5 years worth of tasks using LLMs.
Your problem with the statement is that they didn't provide a source. Maybe express interest in the facts that might support that instead of freaking out over perceived insanity.
