The fact that the notion of contact-tracing wasn't immediately met with howls of laughter and/or outrage is perhaps the most depressing aspect of 2020, a year with some extremely stiff competition in the "well, now, that's depressing" category.
Unless you're arguing we are innately incapable of doing that? That feels like defeatism.
The problem is the government incompetence and/or malfeasance, not contract tracing itself.
Not so.
