It seems to me that an awful lot of money that could be spent on cinder block walls, razor wire, and private security is instead fueling pipe dreams of avoiding those things with some sort of matrix-type escapism.

I would bet that they get more long-term traction out of the walls, razor wire, and hired guns.

The most telling thing about these projects to me are how sheltered the bubbles of existence are for tech execs and their financiers.

Do they think there won't be heroin or meth addicts because of VR? Do they think that neurotic kids raised on legal meth (ADD pills) and legal heroin (anti-depressants) will suddenly be happy to go to work and shuffle the spreadsheets because there's VR goggles in the middle? Do they think VR headsets will make people want the soylent green when there's not enough farmable land left to feed the world's growing population? Do they think it'll be harder for a burglar to knock them over the head and take their stuff when they're zonked out on sleeping pills and alcohol, being aimlessly driven around town by their hopelessly lost Tesla which just had its GPS antenna fail?

All of those things aren't abstract things that "just happen." They are created by the current culture. How ignorant must the current culture's tech execs and finance execs be of their own shadows, to think they can just put sunglasses on and make those things disappear?
