Nah I agree with him. Spinning disks were always a huge bottleneck (remember how long MS Word took to open?) and SSD's basically fixed that overnight. The CPU advancements were big, but software had a chance to "catch up" (i.e. get less efficient) because they it was a gradual change. That didn't really happen with SSDs because the change was so sudden and big.

I'd say software never really "caught up" to the general slowness that we had to endure in the HDD era either. Even my 14 year old desktop starts Word in a few seconds compared to upwards of 60s in the 90s.

The closest I've seen is the shitty low end Samsung Android tablet we got for our kids. It's soooo slow and laggy. I suspect it's the storage. And that was actually and upgrade over the Amazon Fire tablet we used to have which was so slow it was literally unusable. Again I suspect slow storage is the culprit.
