I have quite the opposite opinion. Humankind has a lot of problems, but this part is done well with their approach. With ages being short and cultures being mainly the choice of focus (food, industry, science, etc.) I wouldn't like to not be able to choose my focus. Or to be stuck in the initially chosen focus, i.e. start focusing on food -> produce a lot of food -> have to choose food civ again.To be honest, if Humankind had a system of prerequisites for choosing a culture - such as how you played in the previous era or which culture you're switching from - it would have been a perfect approach.
For Civ7 unlocking looks much better, because unlock conditions we've seen so far match the future play style. I.e. you don't consider mountain-focused civ (Inca) unless you have some mountains.
