I plan to as well until society shapes up in a lot of ways. I think historically there were better options for people, but over the 20th century (watch the excellent documentary “Century of the Self”), marketing took precedence over quality and by the end, we have a vast majority of incredibly unhealthy options for the cheapest prices, while quality foods are both hard to find and much more expensive. Soylent to me represents a reaction to this, something that restores the balance.
I have no regrets, I was sure to try most of the world’s cuisine many times over before making this transition, even cooking quite a few cuisines myself, which I will continue to do from time to time.
But in the next few decades, many things will have to give. Global society might have to simply agree to give up beef as the footprint it costs is becoming too much for the planet to bear (unless the population is somehow greatly downsized). People who ought to feel guilty about the way they coerce the food and beverage industries in terrible ways will have to begin to feel guilty, or retire and be replaced by a new generation which hopefully has a stronger moral compass than the previous.
You can draw a lot of parallels across trends in the 20th century - the same people who were doing this were also shutting down any potential for electric vehicles so that scarcity-based fossil fuel industries could thrive over the decades, at the awful expense of climate change and an uncertain future. It’s hard to say if any of these people knew what they were doing and did it anyways or not - but if they did - it is difficult to fathom how they could sleep at night.
But anyway, at least there is a new generation, largely on the West Coast of North America, who are working hard to set things right again. And anyone in this circle of new companies who is doing their part right, is someone I would support until the end.
