Maybe so. Because of hardware security flaws and its workarounds:

Citando:
"Why Spectre demands more elegantly coded software
Write it well, write it efficiently, write it as though the underlying hardware isn’t going to get any faster. Because it isn’t"
(...)
"There are some Spectre-immune systems, but they tend to be slow or old or both. The Raspberry Pi is one and I’m writing this article on another, a pre-2013 Intel Atom box. It doesn’t do out-of-order (OoO) execution, but therefore it doesn’t do anything particularly quickly. This is now the choice facing everyone who cares about security: fast and flawed or slow and safe (or at least safer).
Until that changes, until a new generation of chips somehow circumvents the flaws and gives us full-speed computing without speculative execution vulnerabilities, software developers must step up and make a difference. Yes, efficient coding is suddenly back in fashion, because developers can no longer assume that tomorrow’s hardware will be faster than today’s. But what does this mean in development terms?"
