I don't know what today's architecture will be called in the future. In the past architects would form groups, name themselves, write manifestos and otherwise promote their ideas in magazines and exhibitions. Historians don't need to make up names and assign categories when the architects do it themselves. But architects don't really do that anymore, and aside from that, there's not an expectation that anyone follow one universal architecture and there's less thinking in terms of movements. Architects act more individually (maybe this is a way that historians can characterize today's architecture).

To demonstrate this of course you can look at the buildings you posted which really have nothing to do with each other except that they use glass.

And while they use glass, there hasn't been "an architecture of glass" for a long time. From about the 1870s to the 1930s, and especially in the 1920s, glass and its architectural implications were explored. There was the Glass Chain, which was an almost cult-like group which thought glass had utopian, spirit-cleansing properties. There were Mies van der Rohe's two glass tower designs which at the time were unbuildable but opened up a few theoretical ideas. One being that with opaque materials architects dealt with light and shadow while with glass architecture reflections join that group. Another idea is that a building could be both universal and contextual at the same time. Universal in that you could put the exact same building anywhere and local in that the glass would reflect it's surroundings (the building would literally mirror its context). Other ideas are that glass can let in more natural light and views, and that glass walls can connect with nature better. Glass walls also change the way that space was made, because before then, in order to enclose an area, you had to make an opaque wall which forces you to define space. But glass walls can enclose an area without defining space.

These are just a few examples of the theoretical sides of glass. Architecture "about" glass. But I think by the time world war 2 came around, architects had worked out the architectural implications of glass, and from then on glass was either used when technology allowed old ideas to be executed (like the 1970s context reflecting mirrored glass), or it was simply used as a building material like brick or concrete.

The examples you posted are of buildings that use glass simply as a building material like any other. There's lots of glass in those buildings because the architects thought there should be lots of windows. Big windows seem to be well suited to skycrapers. Other than in skyscrapers though, I don't think glass is particularly more common than brick or concrete or wood or metal.
