That's not how the real world works. A lot of manufacturing equipment and test stands were developed using LabView and used NI cards to control equipment and take data. The people who developed all that stuff are long gone and the new people neither understand the old stuff nor do they have time to spend many months spelunking into the guts of the old software to maintain it. Their managers are also very reluctant to change anything since it means very expensive downtime for an entire assembly line. Downtime can cost tens or hundreds of thousands of dollars per month. Everybody wants to keep the old stuff running as long as possible -- generally several decades.

I have no experience in the banking industry but I do hear the same considerations I see in manufacturing exist in banking software. Any change is fraught with major risk (millions of dollars in loss) so change is avoided as much as possible. I see lots of people on HN talk about how change and churn is avoided in banking software ... the same applies to manufacturing.

The Rasberry Pi comment is laughable. I'm not talking about toys for hobbyists. I'm talking about computers running software controlling cards costing tens of thousands of dollars running physical equipment of equal or greater expense. Nobody will hire a hobby hacker to light a few LEDs with a Pi when doing factory automation.

Also, it's laughable to talk about power consumption when the PC is controlling an industrial system that's using many kW or even MW of power. At that level, 10W vs 100W is noise.
