It already has changed and is very different from what it was 50 years ago, let alone a hundred.
How many of today's radio amateurs are capable of designing and build their own multi-band, multi-mode transceiver from scratch? How many could design and build an SDR transceiver from scratch? And with the availability of cheap hardware, how many are inclined to do so and/or are currently operating using a recently built & designed homebrew multiband, multimode transceiver?
So yes, it has changed, and the hobby (or pursuit, as you prefer) is continuing to change. Many view change to be a good thing and embrace it. Others are scared of it and are desperate to cling on to the past.
Some things haven't changed though - For instance, even though getting a full licence is how harder than back when you got yours (higher standards?), some of today's amateurs are still prepared to put in the work, despite the fact that a minority of the old guard ignore them or look down on them whilst they're still progressing through the lower levels.
It's not too late - if you'd like to help to make sure that the hobby (or pursuit, as you prefer) doesn't die, I'm sure the community would welcome your support and input.
