Linux and open-source software will be hotter than ever, but the real changes will be in how they're secured.

Linux is everywhere. It's what all the clouds, even Microsoft Azure, run.  It's what makes all 500 of the Top 500 supercomputers work. Heck, even desktop Linux is growing if you can believe Pornhub, which claims Linux users grew by 28%, while Windows users declined by 3%. 

Open-source software is also growing by leaps and bounds. According to Gartner's 2021 Hype Cycle for Open-Source Software (OSS): "Through 2025, more than 70% of enterprises will increase their IT spending on OSS, compared with their current IT spending. Plus, by 2025, software as a service (SaaS) will become the preferred consumption model for OSS due to its ability to deliver better operational simplicity, security, and scalability."
