Regarding expanding role:
The scenario I'm somewhat worried about is that instead of 1 PM, 1 designer and 5 developers, there will be 1 PM, 1 designer and 1 developer. Even if tech employment stays stable or even slightly increases due to Jevons paradox, the share of software developers in tech employment will shrink.
I think more likely - no PM, no Designer, one stressed out Mega PM-D-SWE
1 PM, 1 designer, 1 developer, and 10 SREs to clean up the mess.
