Vocabulary

This lesson introduces 5 key terms drawn directly from the article:

• A double-edged sword — something that has both positive and negative consequences.
• To future-proof (something) — to design or update something so it will remain useful and effective in the future, despite new developments.
• To exploit a vulnerability — to use a weakness in a system to gain unauthorised access or cause damage.
• To err on the side of caution — to be especially careful and avoid risks, even if it might not be strictly necessary.
• A race against time — a situation where you have to do something very quickly because you have a limited amount of time to finish it.

Grammar

This lesson focuses on Speculative language for future possibilities.

When we discuss future possibilities, like the technological threats mentioned in the article, we use speculative language. This allows us to express different degrees of certainty, from strong probability to weak possibility, rather than stating something as a definite fact.

Examples from the lesson:

• Quantum computers could break current encryption methods within the next decade. — We use 'could', 'may', or 'might' to talk about a future possibility that is uncertain.
• Without new security protocols, our data can't be safe from this kind of attack. — Use 'can't be' or 'must not be' to express a strong belief that something is impossible or untrue.
• Developing quantum-resistant algorithms must be our top priority. — Use 'must be' to show you are almost certain about something based on logical deduction.

Key rules:

• Use 'must' for strong certainty and 'can't' for impossibility.
• Use 'may', 'might', and 'could' to express possibility (they are often interchangeable).
• These modals are followed by the base form of the verb (e.g., 'It might happen', not 'It might to happen').

Practical English

Raising concerns about potential risks

In a professional setting, you often need to discuss potential problems or risks without causing panic. These phrases will help you raise concerns, speculate about threats, and suggest solutions constructively in a team meeting.

Phrases you'll learn:

• "I'd like to flag a potential issue regarding..." — use this to formally introduce a concern you've identified.
• "I'm just thinking out loud here, but could this make us vulnerable to...?" — use this to speculate about a weakness without sounding too alarmist.
• "To be on the safe side, we should probably..." — use this to propose a cautious course of action to prevent a potential problem.
• "The potential downside here is significant." — use this to emphasise the seriousness of a risk you're discussing.
• "I'm glad you brought that up. It's something we need to address." — use this to agree with a colleague's concern and validate their point.
