Many people want to be managers to grow their careers but in reality being a leader is more important in the long run. A leader is someone whose authority is earned and people choose to follow as opposed to someone people have to follow because it’s their job.

Tiny Language Models are fantastic. To work around the limitations of context size, focus, and knowledge inherent to small-scale LLMs with ≤7B parameters, the solution is to multiply agents, specialize them, and orchestrate them as a team.

There are two types of complexities. Essential complexity is that of the problem you're solving: it creates value. Accidental complexity is self-inflicted because of bad design, bad tooling, etc. It grows insidiously and slows you down. It's costly and hinders your team's morale. Fix it. Now.
