Upskill and be the best in the path that you've chosen. There's no other choice for those who want to stay employed with the skills that they have. Otherwise, be a jack of all trades and try new things and let's learn how to plant our food in our backyards.
I guess that route is not possible for everyone, each worker can't be a perfectionist and everyone can't be best at work. That's human nature, some workers are more skilled and talented then others but the less talented workers also play their role properly as well.
But, I agree the one who want to perform their duties should improve themselves no matter what as those giant companies don't care about anyone but their own savings and profits.
What is important for any worker out there is for them to improve on their own hard skills. Organizations do not necessarily require exceptional workers all through but most will prefer to have an averagely performing workforce, one with an excellent leadership and management skills. Maybe, robots will perform exceptionally well across all boards, since they can be programmed to have the skills of offering high skilled jobs than humans, however, I know there will be constraints especially when it has do with emotional intelligence which may be an ingredient tailored towards strategically delivering the company tasks.
