I recently gave a talk on “Use of Technology in Education” as part of National Education Policy 2020 (NEP 2020) organized by the Indian Institute of Technology Goa (IIT Goa) where I am a faculty member. This talk discussed not only related sections in NEP (sections 23 and 24) but also focused on aspects related to GDP, investment in education and some past projects in making online/digital education accessible. The talk is available at this link.

Talk on Use of Technology in Education
In Education, Science & Technology Promotion and Public Policy on August 24, 2021 at 12:24 AMTechnology Innovation and Unemployment
In Education, Interdisciplinary Science, Research and Development on September 30, 2013 at 12:48 AMAutomation has increased productivity in many areas. If you look at the assembly line or shop floor of a car manufacturer, you will see automation in its full might. Though you will still find a certain number of workers, their number is far less compared to pre-automation days. You may have also come across call center staff who deal with queries related to insurance, bank related tasks etc. Most of these queries are routine in nature and it is the same kind of information that the staff has to provide to the callers. There is recent news that companies like IPsoft are providing artificial intelligence based virtual call center staff to handle such queries. This is expected to reduce the number of people required in BPOs and call centers.
An aprocryphal tale is about a conversation between Henry Ford II and Walter Reuther. The former was the head of Ford Motor Company while the latter controlled its union. When Ford asked Reuther how he would make robots pay union dues, Reuther asked in return if Ford could make his robots buy cars. Ford got the point that any increase in productivity has to be met with an increase in the number of consumers. Ford raised the salary of his staff so that they could afford to buy cars.
Do you think that an increasing rate of technological innovation can lead to rise in unemployment? If you believe in this, you probably believe in Luddite Fallacy. I would rather suggest to be open to debates on this issue. This issue is far from resolved and new insights keep coming now and then. Two opposing views on this issue can be found here and here published in The Economist and Forbes respectively.
Given the fact that many engineers work on systems which are meant to increase productivity, provide better services, it is only relevant to have a look at an aspect of economics and social change that they are seldom concerned with. It is not so much about questioning what they do rather it is more about understanding the mysterious ways in which the world moves!
Automation & Your Skills
In Design Methodologies, Education on August 12, 2013 at 12:24 AMDuring my undergraduate studies, when I first went to a workshop of carpentry, sheet-metal etc. where they teach you how to work with wood and metal and how to make different shapes and objects with them, I did not understand why an Electronics & Communication engineering major was supposed to learn those things. I am sure that there are many who will question that way and this debate will probably never end. Probably, the best learning outcome of such an exercise is the improvement in our abilities to focus, concentrate, be precise and measure accurately. Also, it helps develop a sense for working with limited resources. After all the quantity of wood or metal that each student is given can be limited and one has to ensure that one gets the work done with that limited quantity. Perhaps such learning exercises should be promoted by also focusing on these learning outcomes.
In today’s world of complex manufacturing, computer aided design tools and computer aided manufacturing have taken over such manual tasks. Once can define and draw any shape using sophisticated design tools and have it carved out by a computer aided manufacturing machine. While these computer aided tools came into existence to deal with complex shapes as well as with the increasing scale of manufacturing, they do not let you have the experience of working with your own hands. So it is quite possible that someone adept at using these computer tools, will fail to bend a sheet of metal at a perfect 90 degrees. So what can be a not so promising consequence of this? Excessive reliance on automation even for simple tasks may lead to a loss of such basic skills. At the same time you run the risk of being unproductive when such computer tools shut down for some reason even if the work does not really require them. Automation is intended to reduce time and manage complexity and scale of operations. It is not supposed to replace acquiring skills by hand where possible.
Another example would be tools like Maple and Mathematica. These are extremely powerful tools to solve mathematical problems. Would you stop learning how to solve a differential equation or how to calculate the area of a triangle by pen and paper method because these tools can do it for you? I guess your answer would be “no” because if your answer is “yes”, you risk a future where people would have forgotten all such knowledge and lost such skills which would instead be built into computer/software systems. A breakdown of such systems would leave you with no option to get back on track!
P.S. The idea for this post came after reading Are We Losing the Secrets of the Masters? This article also mentions about old books which described in detail design of magnets and electromagnets, making neon signs, silver printing, building a forge, blacksmithing etc. Some of these books can now be found here, here and here. A PDF version of a 1896 book titled “Five Hundred and Seven Mechanical Movements” digitized by Google can be found here and associated websites on animation of engines are this and this.
PhD vs Work Experience: The Perennial Debate
In Education, Engineering Principles, Intellectual Property, Research and Development on March 9, 2013 at 11:35 PMThose of you who have ever considered doing a PhD or getting a higher technical degree would have definitely come across this debate on PhD vs work experience. One can find so many articles and opinion posts on this subject. Many of us tend to evaluate PhD and work experience by replacing one with the other. Setting aside financial considerations, we tend to evaluate these two experiences by examining the worth of each when replaced by the other. I think that this approach is improper. PhD and work experience can be/made to be complimentary to each other. Not all work experiences are of high quality and same is the case with PhD granting institutions. Not all companies are alike just the way standards differ across institutions of higher learning. I would not be debating the pros and cons of PhD or of work experience in this post as that subject merits far greater analysis than what I can put in a blog post. However, taking a broader view, I would say that a PhD program lets you get out of your comfort zone and explore complex, unbounded problems which could be fundamental or applied in nature. It teaches you to learn, examine (and re-examine), critique, argue and persuade using facts and figures. Its not that there are no corporate jobs where one cannot learn these very things. But they are far and few and the degree to which you need to exercise your brain varies across them. As an example, you can be a great lawyer, corporate, civil or criminal, but being a great lawyer is different from being able to comment, analyse, contribute to the very subject of jurisprudence which gives rise to all judicial activities. Another example: you can be an excellent system on chip architect, but being able to get into the depth of power integrity analysis is a different story. Of course you can be a great power integrity analysis engineer too who can apply all sorts of engineering tricks to perform clean power integrity analysis but you need not be able to comment, analyse or examine the principles on which power integrity analysis is based to the same depth as a typical PhD degree holder would do. The point I am trying to make is that “there is space and need for both kinds of experiences“. They need not be present to the same degree in one single person. The utility of a PhD and that of work experience depends on many factors. At the end of the day, you do a PhD because you want to explore, find new things or just sit back and critically reflect on the existing things because other people are busy meeting the demands of the market which has its own challenges!
Software, Patents, Innovation, Ideas: A Curious Mix
In Education, Intellectual Property, Interdisciplinary Science on October 8, 2012 at 6:13 PMFiling a patent is a big thing these days, especially in the academia. It has been there for quite a long time in the industry though. Earlier, it would suffice to publish in top quality journals or conferences, but now patents are the real icing on the cake. Filing a patent is a costly process and it is far more costlier to prosecute it till its allowed lifetime after it has been granted. One needs not only really deep pockets to engage in patent litigation but also an elaborate infrastructure to find out instances of patent infringement.
While a lot of the patents in earlier days would describe an invention/innovation in terms of its parts that make it work with detailed diagrams of parts etc., a lot of patents these days are filed based just on ideas. It is ideas which are getting patented and this is something that many people are concerned about, especially in the software industry. History shows us that similar ideas have been developed by different people independent of each other at different times and it is no different in modern times. Do we really have to patent ideas? Are they patentable? Don’t they stifle flights of fancy and imagination which have helped people in coming up with brilliant inventions and technologies? Where is the tradeoff between protecting intellectual property and protecting flights of imagination? I think that protecting both of these are important. However, the dimension of “time” that patents add to an idea/invention can have an impact as one man’s flight of imagination at time “x” prohibits another man’s flight, even if independent, at time “y” where x > y. It is a curious mix and definitely an important issue to be discussed and debated. You might be interested in reading ” The Patent, Used as a Sword” published by the International Herald Tribune.
