By some definitions, yes. If we looked at 'most tasks done by most users' then browsers cover communication (email et al), organising travel (buying tickets, reserving rooms), chasing deliveries, checking inventories... the list is nearly endless across a wide range of jobs and trades.
CAD is moving to browsers - quickly deployable to users, OS agnostic, modest client hardware requirements, centralised file management for team working, no local files to be stolen, extra processing power on tap. Offline working isn't desirable when other team members need to work to changes you have made and vice versa.
