What's the estimated remaining life of Halley's Comet?
This paper estimates "another 2300 close perihelion passages". Multiplied with around 76 years per period, we get roughly 175,000 years. That's probably only a very rough estimate.

If we take the estimated mass of $2.2\cdot 10^{17}g$ and divide it naively by the estimated 1910 mass loss of $2.8\cdot 10^{14}g$, we get just 786 periods or roughly 60,000 years.

Hence, after about 200,000 years the remnant of Halley's comet will probably ressemble an asteroid, if any.
