| They didn't drive it anywhere because none of them knew how to work a manual gearbox, or stick shift as the Americans used to call it when such a thing was still manufactured. I imagine the three desperadoes were still sitting there cluelessly stirring the gear-stick when the police arrived, responding to complaints from neighbours that somebody was using an angle grinder in the car-park. | They didn't drive it anywhere because none of them knew how to work a manual gearbox, or stick shift as the Americans used to call it when such a thing was still manufactured.

| It would have made a good comic scene in a frat-house movie, except that those movies, aimed as they are at hyper-hormonal teenagers, draw little of their revenue from people old enough to remember what a gearbox was like when it wasn't automatic; when, that is, it didn't do the whole thing for you. | It would have made a good comic scene in a frat-house movie, except that those movies, aimed as they are at hyper-hormonal teenagers, draw little of their revenue from people old enough to remember what a gearbox was like when it wasn't automatic; when, that is, it didn't do the whole thing for you. |
| So there would be nobody to laugh, and the post-pubescent audience would drum their heels impatiently on the heads of the people in the row in front, waiting for the next scene when the frat brats fight to take a peek through the knot-hole in the wall of the girls' washroom. Thus our path moves on irretrievably into technologically determined time, as Confucius said when one of his acolytes invented the pencil. | So there would be nobody to laugh, and the post-pubescent audience would drum their heels impatiently on the heads of the people in the row in front, waiting for the next scene when the frat brats fight to take a peek through the knot-hole in the wall of the girls' washroom.

| Presumably when they move on to become air traffic controllers or risk analysts at the nuclear power plant they will still always have calculators in their pockets.

| One of the many advantages of learning your tables by rote and being able to do mental arithmetic is that you know what order of answer you are after for any given question. If you buy eight dinner plates at £4 each, the total outlay will be something like £30, but nothing like £3 or £300, and if the salesperson, staring dimly at the figure beeping up on her till, says the price is £32,000, you'll know that you should think twice - that's two times once - before handing over your credit card. | One of the many advantages of learning your tables by rote and being able to do mental arithmetic is that you know what order of answer you are after for any given question.

| But without the benefit conferred by a headful of thoroughly memorised relationships, the air traffic controller will be lost, and eventually some of his pilots will get lost, not to mention their passengers. And if the pressure in the condenser pipe is rising by four psi every eight minutes and there are only 32 psi of tolerance left before structural failure, the man at the desk had better realise that he hasn't got all day before he scrambles the reactor. | But without the benefit conferred by a headful of thoroughly memorised relationships, the air traffic controller will be lost, and eventually some of his pilots will get lost, not to mention their passengers.

| These are fantasy scenarios on my part, but Mike Alder, the sardonic mathematics teacher who wrote the article, thinks that the whole of modern society might soon come flickering and fizzing to a halt because the people who make and work the miracle machines can't add up in their heads.

| I had an article to finish that day for a magazine in Chicago. Drafting the piece in my notebook with a biro, I got most of it done during the trip, which took about three and half hours. As usual I spent almost no time reflecting that the same journey would have taken Jane Austen more than a week, and that covering the same distance was even slower before the invention of the horse. I took the speed for granted, and if we had been slowed up for an hour by the rain I would have thought that abnormal. | I had an article to finish that day for a magazine in Chicago.

| We weren't. I got to my desk safely by early evening and I sat down at my computer to begin the task of transforming the draft in my notebook into a document, which I could do the final work on before sending it off by e-mail to Chicago, where it would arrive at the speed of light before close of business in the mid-West. | We weren't.

| During the rest of that week, before I left for a business visit to Australia, I slowly grasped that I was more helpless than I had ever thought. The hard drive eventually got saved by my young friend Idris.

| For day after nail-biting day I couldn't send or receive e-mails. Finally I had to fly to Sydney with no clear idea of whom I was supposed to meet at the other end, because all my schedules were attached to e-mails I couldn't read. Getting to Australia and back in roughly the time it took Magellan to leave harbour, I regained my office to find a new flood ready to hit my computer - all the e-mails that had piled up in cyberspace over the past fortnight. | For day after nail-biting day I couldn't send or receive e-mails.

| I can't go back to all that, any more than the young mathematicians can go back to doing arithmetic in their heads, or the young car-thieves can go back to treading on the clutch pedal before shifting the gear-stick, and then - this is the hard part, as I remember - letting the clutch pedal come up slowly while they steadily tread on the accelerator.

| Last night, my toddler sat on the TV and DVD remote controls, sending a variety of signals to both devices. 12 hours of trial-and-error later, we've managed to get TV reception back, but I fear the DVD may be lost forever.

| Don't forget, some of this is cultural; no young Brit would have any difficulty using a manual, because 95% of European cars are manuals; American technology is geared, forgive the pun, that way because American driving requires less work than European, which has harder geography to contend with.

| That's right Clive, no young people have any brains, we're all pathetic specimens of humanity in comparison to generations past. The fact that most decently educated young people can do such basic arithmetic doesn't seem to dawn on Mr James (who I assume reads the Daily Mail and spends life mainly moaning), but being as all old people are apparently splendid intellects, I'll do a deal, I'll draw a pension and they can apply there computer programming and code writing skills to my job. Then they'll suddenly find that just because we no longer do trigonometry in our heads, doesn't mean we haven't got useful skills. I can write in numerous languages of computer code off the top of my head, without a reference guide and that includes doing arithmetic calculations and complicated logical operations, as can everyone who was on my course, can Clive do that? Or is it just possible that while our educations were different, both are relevant?

| I would totally disagree, the way forward for the human race IS to rely on things we don't understand, teaching every new generation the same stuff over and over is utterly pointless.The human brain has so much more to offer when we release it from the mundane task of remembering facts. When we can instantly draw on any knowledge, learning it ourselves will become completely irrelevant.It'd just a matter of convention, individually we don't know how our brain moves our arm, it just 'does', if we had to teach each newborn the whole process from neuron to muscle we would get nowhere.Well learning all facts is just as restrictive. learn it once, archive it for all to use.Just like Google has ended the office quiz banter, total information avaliability will end the need to 'Learn'.Chris, Hull | I would totally disagree, the way forward for the human race IS to rely on things we don't understand, teaching every new generation the same stuff over and over is utterly pointless.The human brain has so much more to offer when we release it from the mundane task of remembering facts.
