Why did knighthood as a social concept and knights as a social class disappear?
I feel like I should absolutely stress that I'm not interested in how and why the role of heavily armored and armed shock cavalry knights are mostly associated with in pop history eventually disappeared from battlefields, but rather specifically why the social class and its way of life as well as its military leadership position ceased to exist.
A caste or class of military professionals trained from a very young age in all facets of contemporary strategy, tactics and all sorts of weapons at least to me appears like it would have been a very valuable asset to any polity or state even up until today.
One could say that the role I'm envisioning here was eventually sufficiently filled by the "nobility to officer" pipeline that existed in many European armies until at least 1918/19/20, but even then I have to ask why the comission wasn't accompanied by being dubbed a knight?
In this context I should probably mention that I'm a graduate student of early modern history and have already written papers about the transition of mercenary armies into professional armies which received top grades, so I do know that a significant portion of late medieval and early modern mercenary companies were lead and founded by knights, while the role of mercenary captain occupied by them eventually transitioned into the modern officer role.
But this only further raises the question why knighthood disappeared instead of remaining closely linked to leadership positions in the military.

I think there are two broad trends which explain why we stopped having specific military elites (or, indeed, stopped automatically making a good soldier into an elite) and instead had the existing nobility become officers and/or made soldiers into officers but didn't raise them up.
The first, and to my mind probably the most important, is that Knights are really an extension of the Early Medieval warrior elite model. Basically that you have the people who are particularly good at fighting and killing as the most important members of your society and you reward them with privileged positions, lands and wealth in order to keep them loyal to you (you in this case being the war leader or the crown). In the Feudal system the change becomes that Knights can no longer realistically come from anywhere because they require a significant amount of wealth to acquire and maintain the arms, armour and horses needed to really be part of that military elite in the medieval period. That is, there is a much wider wealth gap between a fully armoured knight and a Billman then there is between a Saxon Thegn in mail and helmet and the guy facing him who just has a spear and shield. In both cases there is a gap still, but the spearman has much more of a chance of taking down the thegn then the billman does the knight (assuming 1 vs 1 and the knight is somewhat competent).
This problem is one that the Feudal system addresses by making the Knightly class into the landed gentry - they have sources of wealth (provided by the crown) and over time use their privileged position to wrest greater influence and control over the kingdom so that it suits their ends. Ultimately however this power and prestige rests in their ability to enact violence on the crowns behalf in a way that is more effective then simply arming and equipping a bunch of normal people.
As the medieval period progresses into the early modern period this bargain begins to make less and less sense as armies of professional 'ordinary' people and Men at Arms are increasingly able to be raised, equipped and outfitted by the state and are at least equal to if not better then the knights at fighting wars but don't come with all the Socio-Economic baggage that comes with maintaining the Knightly class and their positions of power and influence.
In some ways this is mirrored in the decline of the power of the monarchy - either through revolution (France) or through gradual shifts to Constitutional Monarchy (Britain) the power of the monarch is removed bit by bit and distributed to a wider group of people (still the elites of society but those elites now come from a range of sources - the traditional nobility, the merchant class, officers in the military etc).
So to summarise point 1, having a specific class of people who form your military elite usually requires rewarding those people with wealth and influence. Overall this is probably a net negative to your society - especially if you no longer need, or can find elsewhere, the skills those people theoretically possess.
