I don't know what you mean. Maybe you just don't pay attention?
A few years ago transactions were limited to 15 transactions per second, today there are multiple ways to achieve thousands of transactions per second[1]. A few years ago privacy didn't exist and now there are multiple ways to achieve privacy [2][3]. A few years ago end users had to remember long complicated strings to send a transfer or to restore their wallets and now there are easy ways to transfer to human readable names [4] and social wallet recovery [5] if you lose your funds or make a mistake. Argent alone is a huge increase in usability for end users.
There are more but if you even look at these metrics then things are improving at a great clip. Faster than the early web even.
