There is really very little that is 'left-wing' about this manifesto that describes itself as such. It's basically: 'more technology! don't look backwards... forwards! neoliberalism is hindering productivity and progress... onward to post-capitalism! we need technology! ..... the left has these errors; *lists a few* ! uh...so... yeah... accelerate!'; it's not left-wing if there's not a single concrete plan of 'left-wing' action proposed lol.
They dedicate a total of one, four line, paragraph to discussion of class and proletarian identity. Within it they extremely briefly describe a need to "knit together a disparate array of partial proletarian identities"; yeah, that could be an interesting line of thought, but they really don't meet the bare minimum criteria to constitute an idea. Nor is there a single mention of the means of production or private property. Marx and Lenin are given a couple of passing mentions, as is Deleuze + Guattari and Nick Land; indeed, Land is perhaps the foremost point of reference here, although the high coefficient of deterritorialisation that at least made Land interesting is missing. This isn't to say, of course, that new ideas and doctrines must always be explicitly indebted to the past; more that if one isn't going to clearly draw upon the vast reservoir of political theory available, they better be providing something incredibly singular or at least coherent. #ACCELERATE misses the mark on all fronts.
The problem is that once all 'left-wing' elements have been removed, all that's left is some strange techno-neoliberal admixture - the very thing that the authors decry. For all of their critique of neoliberalism and calls for 'post-capitalism', by eschewing any and all critique of capitalist structures - private property, alienation of labour, surplus value etc. - they end up right back where they started, with nothing more than vaguely futuristic neoliberalism. I mean, hell, there are even points when they go full auth-right: "The overwhelming privileging of democracy-as-process needs to be left behind. The fetishisation of openness, horizontality, and inclusion of much of today’s ‘radical’ left set the stage for ineffectiveness. Secrecy, verticality, and exclusion all have their place as well". If this is your theoretical starting point, I hate to imagine the disfigurations and mutations that would occur in reality.
