There is a huge difference between buying a solar panel once and having it generate energy for the next 30 years vs. buying a barrel of oil now and consuming it by next week.
It's the same difference as buying a house now and owning it until it collapses vs. renting a house and being at the mercy of your landlord, or buying a piece of shrink-wrapped software and using it for the next 18 years vs. renting a SaaS subscription that provides a different product next month.
Old hardware or emulation of old operating systems on new hardware.
Quite common on old industrial machinery and other capital equipment like lab equipment. San Francisco BART for example has to scrounge eBay for old motherboards that still allow DMA to parallel ports via southbridge because it’s too expensive to validate a new design for controllers.
I have a G5 with a bunch of old boxed software that runs as well as it did the day I bought it. And an Xbox 360 with the same. Not everything has to keep up with the times.
Not all software can be sufficiently insulated from external changes, but almost all software I care about can be. My normal update cadence is every 2-3 years, and that's only because of a quirk in my package manager making it annoying for shiny new tools to coexist with tools requiring old dependencies. The most important software I use hasn't changed in a decade (i.e., those updates were no-ops), save for me updating some configurations and user scripts once in awhile. I imagine that if I were older the 18yr effective-update-cycle would happen naturally as well.
My gut reaction is that the software you're describing relies heavily on external integrations. Is that correct?
He had upgrades, but I was running Kubuntu about 20 years ago, still have a bunch of Red Hat and Mandrake ISOs from the early 2000s, and can confirm they still work.
Beside, on the rate earth materials, it just happen that China is able to exploit it cheaply but other countries also have access to them and could very well exploit.
> other countries also have access to them and could very well exploit.
only in your wet day dreams.
let's just look at Gallium which is arguably one of the most critical for defence. to produce 100 tons of Gallium, which counts for 10% of the global supply each year, you have to have 200 million tons of Alumina capabilities. "other countries" won't be able to do it, as they don't have affordable electricity and skilled workers to make the Alumina business itself profitable. how they are going to use or sell those Alumina? to absorb loss of 2 million tons of Alumina for each 1 ton produced Gallium, "other countries" will have to lift their Gallium prices to stupid level.
that is assuming Chinese choose not to fight back on the Alumina front - they control 60% of Alumina production worldwide, they can just flood the global market with cheap Alumina to bankrupt your Gallium production.
remember - 2 million tons of Alumina for 1 ton of Gallium.
Well I am referring about rare materials for battery, energy storage, solar panel because the discussion was about that.
I don't know about defense needs, could be true, but I guess they are much less important in volume that the other. You may be able to store them in case of disruption.
>It's the same difference as buying a house now and owning it until it collapses vs. renting a house and being at the mercy of your landlord,
I always take issue with the expression "buying a house now" when you actually mean "pay a mortgage for a house now". With a mortgage, you are at the mercy of the bank and whatever contract you signed. With a rent tenancy, you are at the mercy of the landlord and whatever contract you signed. A landlord will wake up tomorrow and tell you to leave, you have some notice period. Your fixed period deal ends and you can only get a deal that triples your rate.
It's like when people say that self-employed people have no boss, your customer becomes your boss. And you always have one. Everyone that exchanges services/products for money has one.
For some people "buying a house now" actually does mean "buying a house now, with cash". My mom bought her last house with cash - she just rolled over the money from the sale of my childhood home, which they paid off in the 80s. I needed a mortgage for mine, but now that I have it I'm clinging to my 2.75% rate, it's less than I can make with basically every other investment. In Silicon Valley it's not uncommon for people to buy houses (even $4-6M ones) with cash because they're sitting on an 8-figure exit.
Even besides that, there is a dramatic difference between a typical (U.S.) mortgage that locks your payments for 30 years, and a month-to-month rental where your rent can go up next month. It's the same difference as buying a solar panel that fixes your costs for 30 years vs. paying whatever electricity rates the local utility charges this month.
(And there is also a dramatic difference between having 1 boss vs. 10 clients vs. 1000 customers vs. 3 billion users. The amount you can ignore any one of them goes up exponentially, and the risk that they will all stop paying you goes down correspondingly.)
"For some people", yes nowadays, it's for wealthy people only unless it's a house in the middle of nowhere.
In a tenancy, your rent can go up but most decent countries have legal restrictions in regards to how many increases you can do in a period of time and by how much you can increase it at any given time, and gives tenants legal tools to contest it if needed. And you still get the freedom to move to a different city without losing money. Here, most people don't do anywhere near 30 year mortgages so maybe that's more of a US thing.
In an ideal world, businesses would have customers that are all equally valuable. But in the real world, many businesses have a few customers that account for most of the revenue and the rest of the customers. Those few customers become your boss and they indirectly dictate significant parts of your business because an average customer not spending as much will be ok but a major customer not spending as much will get you sweating and looking at your cashflow.
