Instead, make that:

require 'fiber'

root_fiber = Fiber.current

f = Fiber.new do
  if Fiber.current.eql?(root_fiber)
    puts 'root fiber'
  else
    puts 'not root fiber'
  end

  Fiber.yield "hello world"
end

f.resume

if Fiber.current.eql?(root_fiber)
  puts 'root fiber'
else
  puts 'not root fiber'
end
