Doubtless also is the proposition that more earth-mass planets orbit these small stars than orbit sun-like stars. These stars will never go nova and will shine for trillions of
years. Seems like advanced civilizations of space aliens would find advantages
in residing on and around stable and predictable red dwarf planets, that is if they can find ones that are not tidally locked. Even if red dwarf planets are tidally locked, and their surfaces are hostile to habitation, giant wheel space habitats/ships could enter stable orbits about stable and perpetual dwarf stars and collect free energy for trillions of years. Heat-death of the Milky Way is at least trillions of years in the future. Looking for intelligent life around sun-like stars might not be the smartest plan.

In a similar vein we should consider that most stars are binary because orbital
mechanics do not allow very persistent trinary systems. Planets associated with
trinary star systems are ejected into interplanetary space. Countless billions
of dwarf stars and unassociated planets are cruising through interstellar space
on random paths.

Earth science has no present means of detecting unassociated planets in interstellar space. An advanced civilization desiring physical interstellar travel might think building giant suspended animation or countless generation interstellar ships impractical, but hitching a ride on planets associated with red or brown dwarfs headed in the “right” direction might make sense. For all practical purposes, a red dwarf star is a perpetual source of radiant energy and most are headed somewhere else.

A data set of one isn’t much to build on, but the article suggests about every 100,000 years an advanced Sol civilization could hitch a dwarf star ride to somewhere else. Are dwarf stars interstellar space liners for advanced civilizations?
