ELI5: Why hasn’t windshield wiper blade technology improved much?
gpt
They have in many ways.  But a lot of the improvements are either not noticeable or on the more expensive options that people don't get.

Some examples: The connections are a lot better than they were 30-40 years ago, making them easier to install; the top springy area--and that's a technical term--improved to help move water; wipers are available that leave a polymer on your windshield to make water bead, thereby improving visibility and the wipers effectiveness.

Windshield wipers are a LOT better than they were in the 80s & 90s.
