I don't feel like being dependent on LLM coding tools is much of an issue, you can very easily switch between different vendors. And I hope that open weight models will be "good enough" until we get a monopoly.
In any case, even if you are afraid of getting too dependent on AI tools, I think everyone needs to stay up to date on what is happening. Things are changing very quickly right now, so no matter what argument you may have against LLMs, it may just not be valid any more in a few months
