AI was a hot topic at this year’s Web Summit, and rightly so. But amid the buzz, one keynote stood out for its critical, grounded perspective on where the current AI landscape is falling short, and where meaningful progress might actually happen. Below are our summarized insights from the talk, which pulled no punches when it came to the limitations of large language models (LLMs) and the risks of inflated expectations.
Current LLMs are just one slice of AI’s potential: Today’s systems represent a narrow corner of what AI could become.
Fundamental flaw: LLMs lack structured database records, making them prone to hallucinations.
“Prompt and pray” problem: Even with the best prompt, you often hope it works — a sign of unreliability.
Hallucinations haven’t gone away: Despite 25+ years of research, they’re still common.
Questionable ROI: ~$500B spent on development; just $7B in actual revenue to date.
LLMs = autocomplete on steroids: They lack true reasoning or logic.
No formal reasoning: Can’t perform formal proofs like traditional computer systems (e.g., Windows device drivers).
Context buffer issues: Limited context leads to inconsistent and unpredictable output.
Diminishing returns from scaling: More data isn’t necessarily solving core issues (e.g., GPT-5 hurdles).
Security concerns: Claude was recently found vulnerable to prompt injection/jailbreak attacks.
Neuro-symbolic AI — a hybrid model combining neural networks and symbolic logic — offers a path forward:
✅ Better interpretability
✅ Easier to debug
✅ Allows explicit constraints
✅ Can be directly programmed
Example: AlphaFold’s success in protein folding is credited to this hybrid approach.
AI bubble signs: Comparisons to WeWork highlight inflated valuations (e.g., OpenAI).
Minimal real-world ROI: A survey of 7,000 companies revealed no measurable bottom-line impact from AI.
Commoditization underway: A price war is emerging.
Nvidia slowing down: 20% growth is still big, but well below previous explosive trends.
Still, some high-value use cases exist:
✅ Coding (hallucinations can be spotted and fixed)
✅ Scientific research
✅ Drug discovery & biology
Major risks to monitor:
❌ Misinformation at scale
❌ Cybercrime potential
❌ Impact on education systems
❌ Deepfakes & media manipulation
