I was reading in Elementary Topology by O Viro, O Ivanov, V Kharlamov, and N Netsvetaev and it caught my attention the following quotes by the authors:
"...As a research field (refering to General Topology), it was completed long time ago ...We warn the students..Do not hurry to fall in love with it too seriously, do not let imprinting happen. This field may seem to be charming, but it is not very active. It hardly provides as much room for exciting new research as most other fields"
my questions: if General Topology was completed long time ago, then what do current General Topologist study ? what sort of questions do they try to answer ?
