It's not so easy.

Computing power can be increased by scaling vertically or horizontally. Vertical scaling has an upper limit, and when one reaches it, in certain contexts, end of the happiness :-)

Case in point: GitLab; they have Go microservices. GitHub was also hiring Go developers, so very likely they've done the same.

Of course, few companies are GitLab/GitHub, but the point is that it's not possible to make absolute statements about power being cheap.

Agreed. Yet even if you don’t reach Gitlab scale, languages like Go and Elixir can help you deliver the same service at 10-20% the cost.

By being able to run your service on a single server instead of ten allows your team to focus on features instead of scaling your application using background concurrency, caching, or “micro-services”.

Imagine what you could do when you don’t need to manage a fleet of web-servers.
