People need to understand that LLMs are not smart, they're just really fancy autocompletion.

These aren't exactly different things. This has been a lot of what the past year of research in LLMs has been about.

Because it turns out that when you set up a LLM to "autocomplete" a complex set of reasoning steps around a problem outside of its training set (CoT) or synthesizing multiple different skills into a combination unique and not represented in the training set (Skill-Mix), their ability to autocomplete effectively is quite 'smart.'

For example, here's the abstract on a new paper from DeepMind on a new meta-prompting strategy that's led to a significant leap in evaluation scores:

We introduce Self-Discover, a general framework for LLMs to self-discover the task-intrinsic reasoning structures to tackle complex reasoning problems that are challenging for typical prompting methods. Core to the framework is a self-discovery process where LLMs select multiple atomic reasoning modules such as critical thinking and step-by-step thinking, and compose them into an explicit reasoning structure for LLMs to follow during decoding. Self-Discover substantially improves GPT-4 and PaLM 2’s performance on challenging reasoning benchmarks such as BigBench-Hard, grounded agent reasoning, and MATH, by as much as 32% compared to Chain of Thought (CoT). Furthermore, Self-Discover outperforms inference-intensive methods such as CoT-Self-Consistency by more than 20%, while requiring 10-40x fewer inference compute. Finally, we show that the self-discovered reasoning structures are universally applicable across model families: from PaLM 2-L to GPT-4, and from GPT-4 to Llama2, and share commonalities with human reasoning patterns.

Or here's an earlier work from DeepMind and Stanford on having LLMs develop analogies to a given problem, solve the analogies, and apply the methods used to the original problem.

At a certain point, the "it's just autocomplete" objection needs to be put to rest. If it's autocompleting analogous problem solving, mixing abstracted skills, developing world models, and combinations thereof to solve complex reasoning tasks outside the scope of the training data, then while yes - the mechanism is autocomplete - the outcome is an effective approximation of intelligence.

Notably, the OP paper is lackluster in the aforementioned techniques, particularly as it relates to alignment. So there's a wide gulf between the 'intelligence' of a LLM being used intelligently and one being used stupidly.

By now it's increasingly that often shortcomings in the capabilities of models reflect the inadequacies of the person using the tool than the tool itself - a trend that's likely to continue to grow over the near future as models improve faster than the humans using them.
