SRE is much more than just incident response.
I thought this needed to be highlighted since many are talking about "AI SRE", which mostly focuses on incident response.

Consistency is underrated.
Many people believe in a "big bang" event that propels their career. And while there are certain cases where that's true, consistency is usually a better investment of your time.
Invest in being consistent and you'll reap rewards.

Reliability, like any other feature, needs to be prioritised accordingly.
There will be times where reliability work will be the priority. Other times, product features will be the priority.
And so on.
If one topic massively overshadows all the others, problems will arise.

For platforms to be valuable they need to be force multipliers.
That means being more than the sum of its parts.

You always need to take roles and titles with a grain of salt.
I often meet DevOps/SREs/PlatEng all doing very similar jobs.
I also often meet groups of DevOps doing quite different jobs. The same applies for SREs and PlatEngs.
Context is crucial.

Some people look down on or think of quality assurance and security as annoyances.
In the age of AI, if they continue to have that perspective, they'll have a rude awakening.

Strive for civil discourse on your teams.
Some of the most creative solutions I've seen were born from discussions between people with completely different views on how to approach a problem.
Promoting diversity lays a good foundation for this to happen organically.

For complex issues, I like runbooks because they allow me to really understand the problem before trying to automate it.
In the long-run, for most issues, I strive for automation. But starting with runbooks allows me to understand the quirks before automation.

More often than not, when people reach out to me at events to ask "should I use Kubernetes", the answer is "no".
That's because, usually, people approach it from the tech side, not a problem they need fixing.
Focus on the problem and only apply tech that helps you address it.

Let's be clear, Platform Engineering *enables* DevOps.
If it doesn't, something's wrong.

Whether you like it or not, reliability and security aren't non-functional requirements.
They're features!
Imagine storing your money in a non-secure bank.
And, as features, they need to be prioritized accordingly.

For many companies, AI is an accelerator of inefficiencies.
For example, if you don't have a fast, reliable and secure way to release software, AI exacerbates the problem.

As an engineer, be curious.
That doesn't mean you should change everything due to the most recent hype.
But it means you should be open to explore new things and evaluate them within your context.

Going to conferences and sharing knowledge with others is a major career boost.
And you don't even need to give a talk or workshop: just have interesting conversations with people. Talk about challenges, what could be solutions for those challenges and share experiences.
