CONTEXT 184 : JUNE 2025 35 Such systems are under active development, and the financial success of OpenAI, makers of ChatGPT, has caused the rate of research and development to increase rapidly, driving the emergence of an ecosystem for knowledge work. These tools are being applied somewhat chaotically. A ‘throw it and see what sticks’ mentality is changing how we interact with computers and will continue to do so until this development phase plateaus. Whether that is followed by further sinusoidal waves of progress or another AI winter (there have been several) remains to be seen, but even if progress stops tomorrow the change that has happened since 2022 has been substantial. How does this apply to conservation? There are several questions to consider: • What tasks constitute the work of a conservation specialist? • Of those tasks, which would suit the involvement of a current generative AI system? • For the tasks where genAI involvement could be beneficial, how can this be done in a way that maximises benefit and minimises harm to the work? • What second-order harms may we need to be aware of, beyond potential harm to the work? This might include harms to society or the environment. • What developments would need to take place for the jagged technological frontier of things genAI to advance further into the list of tasks a conservation specialist carries out? I do not know what we will be doing in five years, but my guess is it will be very similar to what we do now. That said, just as typing an email by computer, and dictating an email to your phone, are similar in one sense, they are also quite different. Concern about genAI, or even hostility towards it, is in many ways quite reasonable. The technology poses problems ranging from increased consumption of natural resources, concentration of power in a small number of places, increasingly tying people to their computers, reducing the quality of work without anyone realising or caring, and more. Let us consider some cases that are already being uncovered. You are a conservation officer working in a local authority. An agent sends you a specification for some works that are taking place on a large historic building, and you need to appraise the suitability of the proposals. The specification is 130 pages long, and most of it is standardised boilerplate. You could either trawl through the whole thing manually, trying to find the bit relating to render specification or guttering. Alternatively, you could do a keyword search, click through all the mentions of a given word or phrase, and hope that everything relevant starts to make sense. Or you could ask a large language model such as ChatGPT, Claude, Gemini or Mistral. Or you are a heritage consultant writing a complex design, access and heritage statement for a regeneration project. Part way through, a new edition of the National Planning Policy Framework (NPPF) is released. You could manually go through the new edition, checking for all the new paragraphs and cross-checking the numbers against the ones in your report. Or you could try a large language model. Or you are an architect exploring some early ideas in an urban context. Your usual tools at this stage consist of direct site observation, photos, sketching, Photoshop and your own experience. However, with genAI suited for image generation, such as Stable Diffusion, you could rapidly explore a wide range of different ideas in context. For instance, here is a regular, free picture of a site in Dorking. Using tools in Stable Diffusion called inpainting and upscaling, I was able to change one of the building’s fronts in just a few seconds. I made it look like it has timber panels and an awning. The two images in this article were generated completely using the image diffusion service Midjourney. This uses text, or text and images in combination, to produce a picture. The initial image was designed to resemble a photograph of a 1960s office development in an English high street. Using Midjourney’s ‘inpainting’ tool, in which an area of an image can be selected and re-generated using a different instruction, I carried out the following changes: • Replaced the highway in the foreground with a public realm scheme consisting of paving, planters with plants, and wide pavements. • Replaced two of the central buildings to simulate a new development of attractive, modern, colourful houses in a row, with gabled roofs. • Replaced the ground floors of this development with a row of shop fronts to simulate a mixeduse development. • Added a pair of street trees with autumn colours into two of the planters. There are numerous intricacies and it is not as simple as this makes it sound. A few architects have become quite technically proficient with this sort of program, and in the public sector generally, there is an impetus to understand AI, though it is still very niche. Central government is pushing in the interests of efficiency and competitiveness. I reflect on a planning system hackathon held in May by MHCLG and the Government Digital Service at www.aienvisions.com.
