Educational technology is useful because

Educational technology is useful chiefly because it makes teaching effective and efficient, improving both quality and reach.

It helps organise content, individualise pace and deliver clear, consistent instruction at scale.

Calling it merely the need of the hour is a vague slogan and states no real educational benefit.

Saying it is adopted by famous institutions is an appeal to authority, not a reason grounded in learning.

Saying it attracts students is only a surface effect and not the core justification for using it.

Educational technology has a hardware side of devices and a software side of instructional design and materials.
