I listened to a pretty comprehensive interview Bernie had regarding his proposal a few weeks ago. My big takeaway was that he fundamentally misunderstands the technology as it currently exists, and while he's skeptical of the motives of these tech CEOs, he's completely bought in on their nonsense claims of fully automating the workforce.
AKA an octogenarian suggesting legislation on a technology he doesn't understand. This is a thing that has bitten Americans in the ass countless times in the last four decades.
