When you spend the money on those things your bank or credit card merchant processes every one of those transactions. Cobol is almost always doing the day-end processing on those systems. Hence, while the products you use don't directly rely on COBOL, the fact remains that COBOL is powering the economic transactions that allow those businesses to exist currently.

My point is, COBOL is responsible for a really small % of said value per value transaction between me and said services. Linux, [Oracle/My]SQL, Java, JavaScript, C, anything from router firmware to Intel cpus powering the VMs is more relevant than said COBOL code.

So saying COBOL powers the global economy is indeed a stretch. Want to say Linux powers it? True, Intel powers it? True. COBOL... not so much. Imagine rewriting every COBOL system in the world, now change that into replacing all Intel cpus, ~~SQL~~ OracleSQL or MySQL databases or Linux kernels...

Edit: saying "SQL Databases" makes as much sense as saying "procedural programming languages", updating it to make more sense

Intel CPUs across the world can almost painlessly be swapped for AMD CPUs right now and only a small fraction of users would have to change anything.

SQL is a very high level of abstraction, to the point where the argument is a bit absurd when compared to a very concrete example of COBOL. Yes, if we had to rewrite everything that utilized SQL then it would take an incalculable amount of effort.

I feel like you're kind of hitting the nail on the head with the Linux kernel bit though -- yes we could replace all uses of the Linux kernel with one of the many alternatives available, but it would take a long time. More likely we'd see a major transition to one of the other available kernels. This is exactly the situation COBOL is in.

All this though -- and I think we're just talking about a semantic difference on the use of "%1 powers the %2". Arguably C, SQL, and Javascript provide the value to users which encourages them to spend their money which encourages further development. So okay, I think I follow where you're coming from. COBOL doesn't power the economy, it's just the most common form of infrastructure for us to extract value from the economy. That sound a bit more correct?

I beg to disagree here, swapping CPUs would definitelly prove to be extremelly costly in every possible way. Not only do the MoBo + CPUs themselves have a cost, but they also do not exist. That would mean a huge spike in AMD (or whatever vendor) demand, one that they don't even have the capacity to manufacture. On top of that, all the kernel optimizations over the years, which have a big impact in the overall costs of a cloud service, would be lost. All that ignoring the logistical side of swapping motherboards and CPUs, transport, risk and everything.

You're right. Let me swap that with OracleSQL or MySQL, that'd make more sense.

Imo the Linux kernel position is not the same as COBOL. COBOL is mainly being maintained, whereas Linux is the current standard for new projects and will remain so for the foreseeable future. If we create a new project running on COBOL, or a new project running on a Linux server, those are two completely different situations.

Yes, exactly my point. The economy is not "powered" by banks, it is powered by those who create economic value, and they do not use COBOL all that much.
