for example, let's consider so-called End User Programming, which is a broad term used to refer to programming done by people who are not programmers but rather just average people trying to achieve a goal

very little consideration has been given toward ensuring that end users can relatively easily take up the task of programming their own computers. historically, more attention was given to this, in fact

what was end user programming like in the 1970s and 1980s?

for the average person, BASIC. by necessity, sometimes, because the software industry wasn't yet distributing as widely, and physical copies were harder to produce, etc.
