Is product dead?

I’m starting out as a pm, wanted to know the future of this role. So i prepare myself for the headwinds.

I do see a high supply low demand situation, extremely less high level roles. Competition from developers, sales personals along with other pms for few roles.

I feel this could cause troubles in my career. So wanted an industry pov on it.

Also, Which sectors have highest requirements of product folks, i can see fintech, saas and commerce as the 3 viable sectors to develop depth according to the startup landscape of today, please do correct me if im wrong..
