Yes a lot of time you invest will be 'wasted', and I am faced with having 'wasted' a huge amount of my time learning languages, programming, etc. etc. This pressure you feel to adapt is actually thrust upon you by people who do not care about your mental health, or humanity thriving as a whole. It is disheartening and normal to feel that our efforts will come to nothing and there are no guarantees. A good question to ponder is why it is that such an 'innovative' and 'groundbreaking' thing can cause such negative impacts and what that portends for the future.
