What do Software Engineers do after the age of 40?

Planning out finances, hence this question. Also, we are the first generation (in most families) to retire from this sector. What is the age of the most senior employee you know in software. Hardly only 10% make it to the board/senior levels. How about the rest? And can we really take on this kind of stress and work after our 40s and compete with the younger generation?

After 15 or 18 years of experience, what do folks do, are there many levels above principal engineer? Do they become CTO ? Financially independent so retire ?

I'm a lead engineer at a small-mid Indian Saas company. Been at the company for more than 6 years (total yoe 8+) and used to like the company and culture, alway top performer. Had been managing my team really well, mentoring them.. juggling multiple projects, reducing tech debt, improving developer experience.. and I enjoyed it. Now the company is trying to transition my role to more of a technical product manager where I have to think about how to improve the product, new features, take customer feedback, understand business analytics, usage, adoption, iteratively improve and deliver value. I'm not sure if I'm ready for this role. I hate this MBA shizz. What should I do? Try to like this, work on it and ace it? or let my management know that this is not what I signed up for.. I feel low at work because I'm not able to meet my expectations (let alone my manager's)

Is software industry oversaturated? Do you feel companies will discriminate with us once we hit 40+ age as more and more people are coming into it? I can see class 6 th and 7 th std kids are doing coding just like we had fad for jee classes. If there is oversupply of enggs. companies, whatever the fate mech and civil branches suffered, cs will bear the same. Should one go for mba( off course from top colleges) ?

What is the plan after 40 yrs who work in IT industry? Do you think you will be able to survive after 40 yrs? Career ladder becomes narrow if you keep going up and after some point you either survive? If you have any thoughts pls share..

What is the actual job of consultant, for example if I am software developer then my job description will be developing application using some programming language but what consultant do what is their role what is the work they do, also who gets more salary, consultant or software engineer

I am curious to understand how the future looks like. For now, I think we have a clear aim. Most might not want to startup as they are well satisfied with solving other's problems. But come to think of it, I have not seen much ppl above 50 years of age in the IT industry. With 90's and 80's generation slowly inching towards that phase, how do you guys think it will shape up? straight question : do we have a chance?
