Interesting to see someone wondering a bit... Isn't that electronics business case the result of trying to sell too many useless products? There are many other, non electronics, useless products sold, sure, but far less expensive to create!
The fact is that there are only two ways for selling a useless product. It has to be cheap, or it must look useful.
Low price is OK if the product does not cost much to develop and manufacture. But this is not the case for electronic products. The only ones to do well are those that can convince customers they absolutely need their useless products.
I agree. There are smart people in every field. Every field has its own percentage of smart and hard-working people. Its not the ROI or the smartness that matters to me being an IC design engineer, its the experience and satisfaction of working and understand such a complicated technology that gives me the most pleasure and excitement.
Years ago, I found out that people in Germany consumy as much chocolate as they consume ICs (by purchasing electronics products ). So, I though by myself: "why bothering with complicated electronics when you can make the same mony by simply mixing chocolate, milk , sugar and a few more ingredients"
