 As the deceased member of the human team was the one who most strongly resisted granting the natives rights, the remaining team members recognise the intelligence of the natives of the planet, and decide that conflict is best avoided.They note that the pace at which the natives are progressing technologically far exceeds that of the human society.One team member even notes that while it may take thousands of years to arrive at working space flight from scratch, it might be "considerably quicker" if you know it's possible from the start, and estimates the natives will have space travel in under 100 years, given the fact they have now electricity (from the power plant), and have working, if damaged, space ships to copy.
