But then those were the days when the world around us was so different.
Televisions and VCRs were not around but the availability of the basic
amenities of life like electricity and water was more plentiful.
I am not saying that the general quality of life has not improved during
the last 30 years. The miracles of science and technology in general and
computers in particular have had a visible impact in improving our living
conditions. What has gone unnoticed is the way in which this has changed
the attitude of the modern practitioners of engineering. Those were
the days when engineers used to combine reasoning ability with an intimacy
felt towards their design - a deep understanding of the behaviour of the
various components - to the point where they could begin to personify their
designs. I recall an incident in which a contemporary of mine while explaining
the metastability of a flip flop circuit had the following to say
:"As is common knowledge, it's considered 'mean' to simultaneously assert
Set and Reset as no self -respecting binary device can respond with dignity
to a command to be both on and off at the same time." Today the interest
seems to be more in what a packaged Computer Aided Design (CAD) software
can do for us. For the most part, the concerns of yesteryears about Ohm's
law & Kirchoff's law, of Thevenin's & Norton's theorems and of
Maxwell's electromagnetic equations have been understood and worked
out by the very select few and either embedded in the CAD software or buried
deep in the functionality of an IC. Today's mainstream designers,
whether they are designing a complex board level product or an ASIC, do
not need to fuss with electronics. Databases, expert systems, routers,
models, simulators and a lot of other abstruse concepts coalesce to eliminate
workbenches , soldering irons and above all those endearing bread boards.
In the rush to design efficiently, we may eliminate time and sweat at the
expense of excellence. This according to me is the road to intellectual
bankruptcy. Maybe my acerbic musings are simply the cynicism coated fears
of a bench hacker confronting the computer age.
Having dealt with the past and present, let me venture into making some predictions about the future designs. I believe that the machine to human interface will change significantly. As systems become more complex, this interface must be made more natural. When the operator does not know what he has to do, the designer of the future must help the operator to understand what is required. That is an extension of the 'context sensitive help' that is an integral part of most of the application software packages of today. The world of virtual reality will change almost all aspects of society. Sitting at home the consumer of the future will be able to visit any market or shopping complex of his choice and order the items to be delivered to his home. The technology of teleconferencing will allow the future citizen to confer with his colleagues from his workplace. Important telephone messages would get automatically recorded and displayed on his computer screen without disrupting his meeting. And the electronics engineer of the future will have to play a leading role in making this happen without ignoring the fundamental principles involved. I have attempted to portray the characteristics of an ideal engineer by highlighting the difference in the mindsets of the two generations of the engineers . I have also emphasized that these two view points should merge, each benefitting from the strength of the other. Now, I request your indulgence to end on a philosophical note by observing that notwithstanding these differences there is a certain element of timelessness about some of the wonderful things around us today that have been passed on to us by the ages . Predictably, these will remain unchanged. Therefore, tomorrow's engineers (just like the young and old of today) while returning home from a hard day's work will still witness the soft orange glow of the setting sun light up the windows of his city. The shout of the neighbourhood children playing in the fading light and the distant call of a cuckoo will help his spirits soar. And back at home his most delightful way of unwinding himself would still continue to be the loud recital of his most favourite verses from Wordsworth or Shelley while taking his shower.
