Mainly because he can't do it.

But board-level electronic design is precisely throwing parts
together, and then selling the result. It doesn't matter much whether
one uses closed-form equations, or instinct, or random selection and
testing. What matters is whether the result sells, and at what price.

The real Art of Electronics is keeping the price up.

Spice totally changed things. Imagination and simulation have mostly
eliminated math beyond simple algebra. The last symbolic integral I
took was maybe 20 years ago and it just confirmed a fet power
dissipation estimate.

It helps to understand what's going on, but it's not necessary. What
matters is if it works.

Psychology, human emotions and prejudices, dominate electronic design.
They dominate science even more; more because we don't need to publish
in peer-reviewed journals to advance our careers. We only need to
design stuff that works.

He's background noise. Ignore him.

But it must be a sad life to obsess on John Larkin. I wouldn't want to
do that!
