(Re)published a piece on the Spectech Blog about how efficiency warps the types of ideas that get support, which ones get killed too early, and which ideas people choose to pursue in the first place.

Although curmudgeonly, the actual scientists who do takedowns of hype-y things have a great record

I think the Heinlein quote holds — scientists saying “that is impossible” is often wrong.

But “this actually existing work is not as exciting as you think it is” is often right.

"The problem with most people's writing is located between their ears"

Lots of people think they need to get better at writing, but nobody thinks they need to get better at thinking, and this is why they don't get better at writing.

This attitude of "doing it right no matter what it takes" is what separates good work from great work.

Was going back through my blog for unrelated reasons and came across this nugget from 2013.

At least I'm consistent.

Imagine if we kept making physical technologies whose form factors changed this much in 12 years. (Pictures from 1945 and 1957 respectively.)

A fun blast from the past (2018). I guess I've been going on about the same things for a long time.

This story has notes of a leitmotif I have heard over and over again

- Genuine breakthrough
- Takes VC money
- Pressure to pivot because
- Failure to scale

I miss the serendipity of discovering other books you want to read because they’re on the shelf next to the book you were looking for.
