Do you think it&amp;#x27;s fair to write that &amp;quot;no one uses PyPy&amp;quot;?. I feel there are quite many companies using PyPy, mostly for web backend. You don&amp;#x27;t see many usages in other usages like Linux distros or ad-hoc scripts, even when the C extensions are not used, because 1) In 95% of cases, the performance is good enough, 2) the warmup slowdown dwarfs the overall gains.&lt;p&gt;Anyway, I think PyPy doesn&amp;#x27;t get the attention it deserves - the performance gains are fantastic and the vision of the Python ecosystem as Python-only packages with occasional lightweight C libraries integrated with cffi looks very nice to me.</text></comment>
