I wonder if operating systems will be relevant a few years from now. Change is hardly new to the technology. Change drives the industry. Change is how come you need to buy new software, new hardware, new operating systems. Change can make things work better, but it’s not unusual to discover that your “upgrade” is a downgrade because what used to work no longer does. You pays your money, you takes your chances.

I grew to adulthood in a pre-computer society. I started working before cable TV, when encyclopedias were huge heavy sets of books and a computer was gigantic and needed a whole building for itself. It ran on punch cards and used weird languages like COBOL and FORTRAN. Even decades later, personal computers were just one step removed from a doorstop, floppy disks were 5-1/2 inches across and really flopped.

Those early machines (personal units, not mainframes) — I hesitate to call them computers — didn’t do much. They didn’t have hard drives. There was no software and no user-friendly interface. I don’t think the concept existed. No WYSIWYG. What you saw was a black screen with lurid green letters that made you feel like you were going blind after an hour or two.

Then … everything changed. First there was Apple and then Windows. Windows didn’t work very well at first, but soon enough, it got better. And then better again.

There were different players and more operating systems in the beginning. Wang and DEC plus a crazy quilt of dedicated word processors and computers made by Commodore, Atari and many others. For a while, I had an Amstrad, a European machine that was almost a computer, kind an intelligent typewriter with a screen. It spit out paper.

Then, everything changed again. Computers started to really do stuff. It was magic!

Everything changed every day. One day, there was a thing called the Internet. I had to buy and install Netscape to use it. After I got connected, there wasn’t much going on, but it was cool to just roam around and see what if there was something interesting going on. Mostly, you bumped into other people looking for something interesting. And then, there was AOL.

You could send electronic mail — email — if you had a friends with computers. You sent them messages over old copper telephone wires and everything happened in slow motion.

Just getting on to the Internet could take … well, let me put it this way. Turn on the computer. Turn on the modem. Go to the kitchen. Prepare dinner. Cook dinner. Serve dinner. Eat dinner. Clean up everything. By the time you got back to your computer, you might have actually managed to connect to something. Or not.

Then suddenly there were ISPs popping up all over the place. I got a super fast modem that ran at a whopping 2400 BPS! Imagine that. I worked in California from my home office in Boston. Cool! Telecommuting was the cat’s pajamas.

By the time my granddaughter was born in 1996, everybody had a computer or two. In her world, computers have always been fast, the Internet has always been the world’s shopping mall. Ebay and Amazon are no big deal.

At age three, she could run basic applications. For her, it’s like electricity was to us: something you use that is always there and always was. I’m sure she can’t imagine a world without it. It’s hard for me to remember that world and I certainly would not want to go back there.

For a brief interval, the rate of change slowed. We drew a collective breath and didn’t have to buy new computers for a couple of years. High speed connections arrived, though most home users didn’t have it right away. Everything kept getting faster and soon, with cable modems, no one could even remember what it was like to try to get onto the Internet using an old telephone line.

Every time you looked around, there was a  new generation of processors, bigger and faster hard drives, amazing super high-definition monitors and speaker systems to knock your socks off.

The Internet became a world-sized shopping mall and overnight, catalogue shopping became website cruising. The Internet was a world unto itself; I played bridge in real-time with a partner who lived on an island off the Pacific coast.

We have computers all over the house and what isn’t a computer is run by a computer or contains a mini computer … microwave ovens, smartphones, digital cameras and GPS units. I have three computers — in my office, living room and bedroom. My husband has two. My granddaughter has 3, but I think a couple of them don’t work any more. My son has two, my daughter in law has one but if she wants another, we have a spares and she can just grab one.

Eight computers are in daily use and only 5 people live here. I feel that we will soon need to get computers for each of the dogs. For all I know, whenever we are out, they go on-line and order stuff. I’m sure Bonnie the Scottie has at least a thousand Facebook friends.

A brief interruption of cable service leaves us wandering around like wraiths, without form or function. Five of the seven primary computers are less than 2 years old  so I figured we were set for a few years at least … but then everything started changing. Again.

Today, it’s all about “the cloud.” It’s still the same old Internet, but “cloud” is the “in” word for stuff stored on external servers. We’re going back to where we began, to using stripped down computers with no hard drives. Instead, everything is stored on someone else’s computer — out there. In the “cloud.” Our data might be anywhere. We have no way of knowing where it lives.

Am I the only one who finds this unnerving?

I can see advantages. When you eliminate memory sucking operating systems and cumbersome installed applications, your computer will run faster. Start-up is instantaneous because your computer doesn’t have to load services and applications. You don’t have to maintain and upgrade big expensive applications and volumes of data. You won’t need ever bigger hard drives, more memory and video RAM. You wind up with faster computers that are less expensive and easier to maintain. It’s a win-win, right?

Or is it?

How much do you trust your Internet service provider?

If your cable company has a bad day or the servers on which you store your critical data go down — even for a short while — you have nothing. As long as everything works like it’s supposed to, it’s hunky dory, but Murphy hasn’t left the building yet.

Whatever can go wrong, will go wrong, and will do so at the worst possible time.

Maybe it’s my age showing, but I would prefer to have data on hard drives that I control. That I own.

The idea of entrusting everything —  from my photographs to the manuscript of my book — to an unknown server somewhere in the world scares the Hell out of me. What if the building in which the server storing my stuff burns down? Gets hit by a terrorist attack? Taken down by hackers? You have no way of knowing what country your data is in, how stable its government is, or how good an infrastructure it maintains. You financial data could be in Pakistan, Indonesia, or Kuala Lampur. Or next door.

Is there a compromise possible? Because when I think about entrusting everything to a cloud, I begin to twitch.

How many times have you been unable to access a web page because servers are busy or crashed? The times when their — or your — servers are inaccessible because of maintenance, repair or upgrade. Or those ubiquitous hackers. What if you need a critical piece of data from a server while its offline? It does happen.

My bank was hacked and they had to send me a new card. Several places I shop — Land’s End, for one — were hacked and I had to redo my accounts because they’d been compromised.

If your ISP is down, you are out of business. If you think your cable company has you by the throat now, how much worse will it be if everything you need to run your life and business is dependent on their services? Facebook and Google already have trouble keeping up with the demands on their resources. How will they manage when they have thousands of times more data and tens of millions of users depending on them for everything from email and applications to data retrieval?

Those of you who are old enough to remember the great Northeast power blackout in the mid 1960s know what I mean when I say that overloaded systems can go down like dominoes. I am all in favor working together with my fellow human beings throughout the world, but at a certain point, when does inter-dependency make us excessively vulnerable?

If you put the world’s eggs in one basket, if the basket falls, that’s a hell of a lot of broken eggs. That’s not an omelet — just a mess.

I worked for more than 35 years in development. That was my world and although I’m not an engineer or developer, I know what’s behind a user interface. For example, modern word processors embed commands in text, but behind the interface, it’s entering the same commands I entered directly on the huge IBM mainframe by hand. It’s faster and prettier now. You get to see how your document will look when it’s printed, but it’s nothing but an elegant wrapping on an old familiar box.

My concern is not the graphical user interface (GUI) that overlays our computer (regardless of operating system), but that these new operating systems are designed to work with “The Cloud” … a meaningless term that represents servers located anywhere and everywhere. We don’t have to know where they are; they’re in the Cloud … kind of like Angels and God. We are being herded toward using external storage and we aren’t supposed to be alarmed that we have no control over it.

We use services consisting of server farms located somewhere on the planet. There is where we store our bank records, personal correspondence, photographs … everything. We use these servers directly when we use “the cloud,” but we also use it indirectly because that’s where our bank, our vendors, the places from which we buy goods and services store their data … or more to the point, our data as it pertains to them.

We assume the people from whom server space is leased are dependable, not criminals looking to steal identities and data … and their infrastructure is secure and won’t collapse from a power outage or hacker attack. And finally, we trust our ISPs to deliver the goods, keep us online so we can access the stuff we need.

Charter Communications is my cable company and controls my high-speed internet access, as well as my TV and telephone. I have difficulty controlling the wave of rage I feel when I think about them. How do you feel about your cable company, eh?

Even if the servers that store your stuff are safe, you can’t get there without a high-speed connection and that, my friends, means your local ISP … cable, telephone, satellite, whatever you use. They already have you by the short hairs. You are not independent and you rely on their services. Does that sound like a great idea? It makes me sweaty and itchy.

Anybody anywhere can build a server farm. It’s a great business that requires a bunch of servers, a climate controlled place to put them, and a few IT people to tend the equipment.

Where are these places? Most are in countries whose government is, by any standards, unstable — possibly dangerously so. How good is the infrastructure? Are they in the middle of a war? Are their electrical generating facilities dependable or sufficient? What protection against hackers do they provide? Are they trustworthy? They could as easily be a bunch of criminals and the data they collect is the mother lode.

I’m not comfy with the idea of entrusting a lifetime of my work to unknown, nameless entities. Google uses servers everywhere, as does Amazon. So does every other “cloud” provider. Your data and mine is unlikely to be in one place, either. It is broken into many pieces that are stored wherever it went when you saved it. You will not know and cannot discover out where your data is, was, or will be.

I won’t get into how links and pointers let us retrieve data, but the potential for error, loss, and piracy is huge. So, I’m not buying into the Cloud, at least not for anything that really matters to me. Call me cynical, even paranoid … but I think that the computer-using public is buying snake oil. I want my stuff on my own drives. Use the “Cloud,” whatever it really is. But have good, dependable external drives too.

Or, as the Arabs say, trust in God, but tie your camel.
