The hobby is many hobbies. If you try to think of all hams doing one thing, or even just having one common set of skills, that's bound to fail. Some hams are into HF antennas and DX phone or CW contacts, same as always. Some hams are into WSPR and other QRSS/QRPP modes, getting around the world on milliwatts. Some hams are launching and working satellites, in all sorts of modes. Some hams are doing digital TV, especially the lucky ones in the QO-100 footprint who can do TV over wideband amateur satellite transpoder. Some hams are playing with various internet-connected radios and repeaters, like the old Echolink/IRLP but now there's DMR and Brandmeister and stuff. Some hams just want to use HTs that don't suck, while off-roading or otherwise in places cellphones might not work. I could go on. It's a hundred hobbies that have a license in common and sometimes very little else.
