This question resolves to my (or whatever judge continues resolving questions on Manifold's) response to the question "Will "mitochondrial endosymbiosis" , as defined by Nick Hall in 2014, be considered by the consensus of scientists the great filter in the Fermi paradox in 2050?", in 2050"?

This question inspired by this twitter post.

Nick Hall, 2014, "Bioenergetic Constraints on the Evolution of Complex Life": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3996473/

If it come down to it, "consensus" is defined as ">80% of people with credentials that would let them get employed (be found in <50% of job postings) in a field relevant to this question".

Disputes will be interpreted as best I (or the resolver) interprets them.
