For all the people pointing out how much smaller the Jedi are now than they used to be, do keep in mind that as per the Ruusan Reformation a significant downsizing of the Jedi was
intentional.
The Jedi Lords scared the ever-loving
shit out of the political types in the galaxy due to their combination of personal and political power, a substantial amount of the Ruusan Reformation was basically about the Jedi promising that they wouldn't do the whole 'Lord' thing anymore and in fact would disarm and downsize, as now that the Sith threat was dealt with forever and would definitely never ever return the Jedi had no need to be a militant order, nor was there any requirement for thousands of Knights.
So yes, the Jedi are lesser than they used to be (mostly, some sects like the Green Jedi are exactly the same as they have always been for example), and they are fully well aware of this because
they did it deliberately. Many of the Jedi, especially the ones pushing the Consular classes over the Guardian and Sentinel classes, would thus argue that the Order is not dying out at all, it has simply adapted to an era without the threat of the Sith or the need for warrior Jedi.
(They would be wrong of course, but they don't know that.)
Also keep in mind that from the perspective of the Coruscanti Jedi,
they are responsible for the last 1000 years of peace and prosperity. They would tell you that their methods are
clearly working extremely well, because since the Reformation the Republic has had 1000 'uninterrupted' years of 'peace' (note my quotation marks), which demonstrably
proves (to them) that they are on the right path.
And none of this is even getting into the subtle and unnoticed effect of the Dark Side Nexus under the Coruscant temple that is slowly eroding the Force sensitivity of the Jedi, because they were apparently stupid enough to not only build a temple on top of a Dark Side Nexus, but then
forget that they had done that.
From an external, omnipotent view point it is very obvious that the Jedi Order is crumbling around itself, but from an internal, in-character view point only the hidden Baneite Sith are really aware of the true scale of how far the Jedi have unknowingly fallen.

EDIT: The Rule of Two with the Sith's chronic backstabbing disease never made sense. That they lasted a thousand years without fucking themselves over is pure author's fiat.
They fucked themselves over
multiple times, and the final 'culmination' of the Baneite plot (ie; Sidious's Empire) was exactly the
opposite of what Bane actually wanted. (Bane wanted an ever growing, ever evolving Sith, Sidious planned to make himself the immortal king forever and the
only true Sith as a way of 'breaking' the Rule of Two.)
So yeah, the Baneite plot succeeded very much
in spite of Bane's incredibly dumb methodology. It is
not a coincidence that it took 1000 years for the Baneite Sith to accomplish anything, nor that it was ultimately Darth Vader who finally ended the line of succession, not a Jedi.
Compare what the Sith of the past could and did accomplish in
much shorter lengths of time, to what the Baneites achieved, and it's no competition at all. The only thing the Baneites were actually good at doing was hiding from the Jedi, fortunately for them
that was really all they needed to do.
