To me technical is a great spec because it increases your armor while buffing your crafted armor and weapons with the proper perk investment. Unless you are set on a netrunner build, I've gotten a lot of value from tech than int because you can craft way more things for money and generate your own resources. 20 INT just to craft 1 copy of a legendary quickhack and tabula when you're done to respec is a gross overinvestment for my playstyle.
I would hold off on some of the moderate rating gigs until they fix the bug to get the remaining legendary quickhacks from 8-10 INT terminals.
i have 4800 armor w 0 points into tech. which is 4000 higher than you even need. and even with 0 points into tech, if you craft the uncommon variant of armadillo or any other weapon/armor mod, you still get epics. can see absolutely no reason to ever spec into tech.
20 into int also give you access to 25%crit chance and 50% crit damage ocular implants, which are 2 slots usually occupied by relatively pointless mods, like make all damage non-lethal and show grenade explosion radius (something the game does regardless)
