Future of countermeasures on military aircraft?

From what I’ve been reading, the newest infared missiles on the block (AIM-9X, ASRAAM) are virtually flare-proof.

How relevant are chaff and flare countermeasures in the 21st century air environment? Do they still have their uses?

And how effective has active RF Jamming been compared to chaff/flare pods these past fifty years?

And how much promise do those new laser-based countermeasures hold? How do they work exactly? I haven’t found much info about it other than walls of text in PDF documents, which my ADHD-and-Prozac-riddled brain is incapable of reading. :p

Anything else in the pipeline?

Your thoughts?
