If you do not have a racial trait then your max tech level for the racial techs in Zero. Nothing more.
I once played as a race with ALL the racial techs. Had to go max negative on most other things to get under the 2000 racial point setting
.
Basically, I traded ships and analysed all of the aliens tech. I got crystalline from the Phong, organic from the UkraTal, psychic from the CueCappa, and temporal from somebody else.
I only had to research religious on my own
Then I sold ships with Organic/Crystalline crossover tech armor for planets, more tech, money, protection, everything
.
When I said protected, I meant protected, not private.
Most races will not be able to analyse your tech or repair it, only those few who have the racial trait can.
That still means most races cannot benefit from the capture of your tech.
