&quot;Sure, programming languages are cool and useful, but so is geometry, and I don’t spend my free time on that either.&quot;<p>:D - I&#x27;m spending this sunday afternoon learning abut geodesic grids (<a href="https:&#x2F;&#x2F;en.wikibooks.org&#x2F;wiki&#x2F;Geodesic_Grids" rel="nofollow">https:&#x2F;&#x2F;en.wikibooks.org&#x2F;wiki&#x2F;Geodesic_Grids</a>) as part of a project to teach myself d3.js.<p>Otherwise - I agree with the author. It was strange seeing programming become a huge thing about 2&#x2F;3 years ago, but realistically, most people don&#x27;t have the mathematical&#x2F;logical abilities to ever get really productive. Which is fine, they should focus on what they&#x27;re good at, rather than beat themselves up for not mastering a quite specialised skill.<p>I gather the growth in coding bootcamps has lowered the demand for junior devs, but there&#x27;s still a huge demand for more experienced people.
