Software is getting slower faster than hardware is getting faster.

Software bloat mostly.

Read "there is more room on top" to get ideas for improvement.

So true. I remember the slowness of the windows Vista era computers and then saw someone had an older windows 3.1 machine that booted right up with no wait time. I almost suspect the extra wait time is intentional because we are forced to endure the bloat that most people don't want running.
