With regards this claim, the UK Scientific Advisory Group for Emergencies (SAGE) addresses it in their recent paper about future evolutionary scenarios [0]. Scenario Four: SARS-CoV-2 follows an evolutionary trajectory with decreased virulence Likelihood: Unlikely in the short term, realistic possibility in the long term. Which makes sense as most transmission occurs in the presymptomatic phase, there's no selection pressure to evolve to be less deadly.
