Putting the aesthetics aside, I am not sure but I don't know that 1/3 of the amount of steel compared to x thickness of glass would be stronger. Thin steel is pretty flexible. We would need a structural engineer to weigh in. 

Wouldn't a steel sheet be lighter for a given amount of strength over a surface area? 

Looks like [steel is ~3x the weight of glass](https://mojobob.com/roleplay/weight_chart.html) per unit of volume, but I bet thinner steel could be used than what we'd use for glass.

Both. People like to look outside and glass is lightweight compared to other materials. The heavier the structure the deeper and wider your foundation needs to be so especially in cities where have less space to build it makes sense for them to use a lot of glass.

I agree with grey but it would be nice to see other materials used.

Too much glass, you think? That does seem to be the trend. Do you think it's for aesthetics or for practical reasons.
