I disagree. Texas has been one of the fastest growing economies in the states. With a lot of technology companies.
Texas isn't the lowest tax or lowest regulation state, though it's a bit lower than California.
I also think the cultural thing is obvious there. Texas is very pro-entrepreneurship generally.
Texas has no income tax, very little government owned land, no zoning in some places, etc. It’s laughable that you try to put it in the “bit lower than California” category. Texas is basically the opposite approach to governance than California.
You can see this effect inside the US. The most “business friendly” states often do not lead in entrepreneurship because they’re culturally more conservative.
