there are reasons why the analogy may not present a complete picture.

Technology will surely do its bit, but there are powerful forces in

society which will not let education reach the masses, unless such a

time when the whole world becomes ‘middle class’, which it will

probably eventually become. Education will open gates for the masses,

which certain interests are reluctant to let happen, as there are many

roles (professions) which educated people would not like to take, but

are nonetheless considered “necessary”. This is the reason the effect

of diminishing variable costs will not be allowed to take full effect,

for instance even when a laptop is unnecessary, many educational

institutions force students to buy a laptop from official vendors. This

is variable cost but probably can be avoided in some cases.
However, if one is talking about pure acquisition of knowledge as

opposed to what is generally regarded as education, i.e., some form of

accreditation by relevant authorities along with acquisition of

knowledge , then technology is doing wonders and will continue to do

so.
