Technologically modernized totalitarianism may be able to implement large-scale oppressive policies without affecting most of the population. In fact the average person may see a net benefit! This would create a more stable society despite the significantly lower level of freedom and self-determination. We may be witnessing the development of this sort of system in China, for example. The average person benefits, but a segment of the population faces brutal oppression with no recourse and must simply submit. (Contrast with the US, where people who face repression can sometimes start over by going dark and moving across the country.)
I find it more likely that a totalitarian system that doesn't tolerate wrong-think will inherently start accumulating inefficiencies among other things. Which can then end up with the collapse of such a regime.
Building a technologically modernized authoritarian state might increase stability for a while, but not thinking is simply not competitive long-term. Unless you achieve total world domination, I guess.
While they may be able to gain power initially, would-be totalitarians will likely be fighting off multiple threats while they consolidate power. The more they have to manage and spend, the less likely they will be to succeed at their aims. You could argue that the DOGE debacle is the most recent and obvious example of this. All indications are that the project failed, and it occupied quite a lot of energy and effort during the critical transitional period of the administration.
