Have most of the stars that will ever be formed in the Milky Way already been formed?

Wikipedia tells me: "According to recent studies, the Milky Way as well as Andromeda lie in what in the galaxy color-magnitude diagram is known as the green valley, a region populated by galaxies in transition from the blue cloud (galaxies actively forming new stars) to the red sequence (galaxies that lack star formation). Star formation activity in green valley galaxies is slowing as they run out of star-forming gas in the interstellar medium. In simulated galaxies with similar properties, star formation will typically have been extinguished within about five billion years from now, even accounting for the expected, short-term increase in the rate of star formation due to the collision between both our galaxy and the Andromeda Galaxy."

The oldest stars in the Milky Way are over 13 billion years old. The sun is 4.5 billion years old and expected to shine for another 5 billion years. According to the paragraph above, it sounds like we (if "we" is still a thing, that far in the future) wouldn't be able to find very many new young stars by the time ours is done. 

Am I right to feel gloomy about all that? In the past I had read that the "stelliferous" era would last a quadrillion years, meaning we find ourselves only in the first 1/100,000th of the part of the universe's lifetime that new stars can be formed. But apparently that doesn't apply to our own galaxy?

Just to throw this out there, the current star formation rate in the Milky Way is something like one a year so, assuming that it's constant (it isn't) that's 5 billion or so stars that will be formed before the Sun dies.
