As of my knowledge cutoff of 2021, President Biden has accomplished the following:
Passed the American Rescue Plan, providing $1.9 trillion in COVID-19 relief funds.
Rejoined the Paris Climate Agreement, committing the US to reducing carbon emissions.
Approved a $1.9 billion plan to reunite separated families at the border.
Instituted a national mask mandate to help curb the spread of COVID-19.
Proposed a $2 trillion infrastructure plan to upgrade transportation, broadband, and other systems.
Rolled back several Trump-era policies, including a travel ban on predominantly Muslim countries and a ban on transgender individuals serving in the military.
Named a diverse cabinet, including the first Native American and South Asian women to serve as cabinet members.
Begun the process of restoring diplomatic relations with Cuba.
Announced a withdrawal of US troops from Afghanistan.
Launched a national strategy to combat domestic terrorism.
Note: This is not an exhaustive list and accomplishments may have changed since my knowledge cutoff.
If those are Biden’s “accomplishments” (note the quotes), then I wish he never accomplished anything ( by ChatGPT’s definition ). The country would have been much better without them.
