Modern lenses have CPUs and a firmware that can be updated even by the
user (m43 lenses, Sigma 35/1.4). Thus the camera lens is becoming a
computer. As such the possibilities are endless, although I think they
lie more in the software/electronics realm rather than in optical world.

In the 60s and 70s we got improved manufacturing process for making great
lenses at a lower price. Though the very best still cost a lot more, the
amateur did not care.
In the 80s we got ED glass. Awesome. And always priced like it.
By the late 90s we got aspherical elements perfected, sometime coupled with
some quality polymers. Now some excellent lenses are even lighter and
better at the corners.
What's next step in lens improvements?
(Those flat lens systems with software-variable focus control look
interesting. It will be neat when they're able to change focal length with
them.)
