What if the programmer is old?

I'm 27 years old and I'm thinking about it. Just keep going up and can't stop. For example, you have been stuck in P7, and a person who is 10 years younger than you has also risen to P7. Since your positions are the same, your abilities are the same, and you are old, and your income is quite good (with a fixed salary increase every year). When you are laid off, you won't be laid off. So if you really want to fight, you have to climb up. When you can't climb up, you have to find a way out. For example, when you are young, you have investment awareness, and when you are old, you should pay attention to preventing risks; For example, multi-contact services are not limited to technology; For example, improve their soft power, political consciousness and expression ability; For example, improve your influence in the industry; For example, contact the society more, be realistic, and take making money and achieving your career as your own responsibility. The most important thing is to have a sense of urgency. Don't think that programmers can be iron rice bowls for life with more money. You can think about it, whether it is an engineer or a manager CTO, it is just a worker contractor. Since the reform and opening up, workers in all walks of life have been popular. With the improvement of productivity, workers will be eliminated continuously, even if the original treatment is higher. In this world, only those who engage in finance, business and politics will never be eliminated (except their own death). So please remember to leave a way out except technology.
