Beyond ‘Green Growth’: Why HRI Needs a Post-Growth Perspective

The field of Human-Robot Interaction (HRI) is at a crossroad. As we design more sophisticated robots for healthcare, education, and the home, we are forced to reckon with that our technological progress is deeply intertwined with an economic model that demands perpetual growth—often at a steep cost to our planet.

In our new paper, ‘Post-growth Perspectives in HRI’, recently presented at HRI ’26 in Edinburgh, my co-authors (Mafalda Gamboa, Ilaria Torre, and Birgit Penzenstadler) and I argue that it’s time to look beyond the ‘green growth’ narrative.

The Problem with ‘Business as Usual’

Climate research has pointed out that economic growth is the root cause of environmental devastation, and the most prevalent ‘rescue narrative’ is that productivity growth will recover through new technological breakthroughs. But, this narrative rarely account for the limits to the planetary resources.

Almost all improvements in user interactions increase energy and resource consumption. The carbon emissions from training Large-Language Models is one example, and emissions from sensors and components are also mainly caused by energy consumption. All parts, both software and hardware, of the robots the HRI community are building and buying are, therefore, (somewhat) harmful to our planet. 

In parallel, we are seeing a growing graveyard of social robots, where many of the robot platforms that the field has relied on are going bankrupt due to not being able to expand and grow beyond academic buyers. We argue that HRI cannot solely rely on the unstable market of social robots and the market mechanisms that the field is deeply tied to, such as software-as-a-service and robot-as-a-service, which by many large companies is often driven by robotwashing. To tackle this, we point to self-built and low-scale robots, even though they are not exempt from the material dependencies of the broader growth paradigm. 

Introducing Post-growth for HRI

Our paper introduces a post-growth perspective to HRI, by inviting the community to shift the focus from quantitative growth to qualitative development. We reuse the metaphor of the snail (broadly used by the degrowth and slow movements) and add a new ring on the snail’s shell—a layer of automation, artificial intelligence, and robotics, built upon already complex structures. While intended to enhance efficiency and productivity, this continual layering risks creating fragility, dependence, and ecological or social imbalance. The metaphor thus warns of the limits of accumulation and invites reflection on how to achieve balance for HRI. 

To help researchers and practitioners navigate this shift, we propose three actionable steps:

  1. Ask ‘Question Zero’: Inspired by the question zero for the use of AI: ‘why AI?’, we, in our version, ask ‘why robots?’. Asking this forces criticality and more detailed motivation for why a robot is needed and for whom. Question zero can also inform research that examines real-world applications in need of critique. Beyond refusal, the question seeks to find cases in need of assessment and possible exnovation.
  2. The Post-growth Manifesto: We suggest a manifesto (see below), that comes with a glossary. Here, we list a number of conventional understandings of robots in HRI based on our reading of the field, in opposition to a list of important notions within post-growth for HRI. It can be a tool to locate, discuss, and negotiate ongoing research, and in doing so, we encourage leaning into the B side to support a post-growth orientation.  
  3. Sustainability Statements: Just as ethical and positionality statements have become standard, we propose a template for sustainability statements. These encourage researchers to reflect on the environmental, social, and economic impacts of their work.

Why This Matters

As HRI researchers, we have the power to define what the ‘future’ looks like. By embracing post-growth, we aren’t ‘anti-technology’. Instead, we are advocating for a future where robotics serves humanity and the biosphere without being tied to the destructive cycle of endless extraction.

We hope this paper serves as a call to reflexivity and criticality. It’s time to consider not just how we build and deploy robots, but for whom and at what cost.
