I feel that the move of decentralization would be long gone by the time we reach 2025.
I see that it would have barely started by this point. Everything is already indexed - that is the internet. You are tracked whether on blockchain or not. Every page, every keystroke, every pause. Just because you can't see it, doesn't mean it isn't happening.
Job security for longer periods generally comes through developing a career that has value to an organization. It is an investment with risk.
