This is not how I expected my message to be understood.

I did not mean to imply that every Haskell programmer has or should
have a retina screen and a high performance GPU — only that, as a
profession, we have way better tools now than back then.

In humanities, it is usual for there to be either a normal
distribution or a Pareto distribution in any large enough sample of
data. So, unlike in precise sciences, a counter-example does not
refute a proposition. What matters is that there is a trend. And there
is a trend associated with larger and finer displays. It dawns on even
the most _«old school»_ people by now. See for example a letter on
Linux Kernel Mailing List.[1]

I have no specific insight about how to optimize readability for
people that listen to code[2] or sense it with their hands. What I am
sure of is that there are better ways to go about it than dwelling in
the past.
