I'll watch it either later today or tomorrow, but as I said, I can understand your hype. When I studied biotech,I had plenty of things in mind that would require their own tech, just because how awesome they were. And I was so focussed on the biotech stuff that I saw all it's facettes. Taking a step back, I found that we have several generic biotech techs already, and while they are not named "CRISPR" or "Plasmid Toolkit", they include this stuff - amongst other.
Then I picked up space as a hobby and again I think that reusable rockets should be it's own thing; different types of engines such as closed-cycle, open-cycle etc would make a good tech, grid fins, vernier-thrusters.... But they are all included in Advanced Rocktry etc. With the possible exception of reusable rockets, which would make a good tech I think.
So yeah, before adding plenty of techs, take a step back and think if your ideas are not already included somehow or if they can be better represented by buildings maybe.
