In 1979 I was paid nearly a month to write a program that would do a linear regression of experimental data and draw a graph of the resulting line on an x-y plotter. Just a few years later, a $100 calculator would do the same thing.

So, yes, it is highly likely that you will eventually see websites commodified to the point that they are produced by children's toys.

But - there will always be something else to program. The skill is not "website programming", it's just "programming".
