Netflix is using FreeBSD for servers. You can't blame everything they do wrong as being a problem with the new hires. They are using an OS older than Linux that changes more slowly than Linux, simply because it performs the best for their specific application. Rate of change isn't the issue here.

In fact that's 90% of what this comment is. Blaming new people and new techniques for problems when you aren't a part of that organisation and don't actually know what's happening.

Working with computers is not the same as working with construction equipment. Some degree of fluid intelligence is needed in this field, no matter how experienced you might be, just like how a surgeon needs steady hands. The people you call greybeards aren't nearly as old as your father is. We are talking about people who are in their 50s and 40s. They don't have that level of cognitive decline yet. Likewise some things like ext4 aren't likely going to be ported to Rust now or even ever. They can keep maintaining them as they are now for the foreseeable future. Plus I don't want people to have to keep working into their 70s and 80s. At some point it becomes elder abuse. Let people retire man.

C has existed for a long time now. We've been trying to replace it for ages, for most of it's lifespan even. C++ actually was one of the new options at one point. I get it seemed immovable only a decade ago, and I think that has lulled people into a false sense of security. In truth it was inevitable it would have to be replaced one day. It's already well outlived the life expectancy of a programming language. Just think about Ruby: created long after C yet has already become mostly irrelevant. You talk about the maximum rate of tool change, but C is one of the oldest tools we have, keeping it around would be almost 0 rate of tool change over decades. If you can't see that C is very slowly dying then you haven't seen the writing on the wall for the past several years. It's on you at that point.

We should look back with pride at everything that has been accomplished with C, and just how long it's been relevant. We can do this while still acknowledging it needs to be phased out gradually.

No one is asking for change that rapid either. Linux started adopting Rust four years ago now. It's probably still going to have C code inside it for at least a decade from now. This isn't some quick change, it's a gradual process. People have plenty of time to adapt, and those who are too old to do so will be around retirement agent if not already dead by the time C is fully phased out.

We of course play plenty of video games together to keep him sharp. We also eat mushrooms, paper when necessary, and he works out a lot. We do all we can, believe me.

Honestly you take more care of yourself and your father than I do. I am only in my 20s and suck at video games. If I took mushies or LSD I would probably lose my mind, assuming it's all still there in the first place. I suspect there is a good reason why people like me only have a life expectancy of 58 or so.
