Something blue-collar-ish, like cleaning, plumbing, construction, repairs. Anything 'trade'. People are significantly less self-sufficient nowadays, and setting up a plumbing business (in my country, The Netherlands) would easily get me a million-euro business without too much effort. If it has to be in tech, I would jump on the latest trend and try to squeeze it quickly before moving on.

Let me by your Poolse schilder haha

Recently I've been thinking it would be a fun and potentially successful challenge to start a non-alcoholic brewery. Problem is, I don't know hardly anything about brewing.

Specifically though, I have struggled with the fact that many "third places" in my city are breweries - there isn't anywhere to go if you want a large, well maintained outdoor space with seating areas, that also has food and drink options, but that isn't a restaurant looking to turn over tables.

A good NA brewing space could provide the casual "come hang out with your friends/kids" third place that a good brewery does, while catering to those looking to reduce alcohol intake or those that don't drink.

I'd pick a SaaS category with plenty of existing (non-VC) incumbents, and build something better that I personally have experience with using, just as I did in 2021.

Why specifically non-VC?

I’m working on something which I think would be a great product but a direct competitor got $25 million in VC funding in 2021.

Making systolic array chips (my BitGrid design) to bring provably secure Petaflops to the masses. They're handy for any algorithm that can tolerate extreme pipelining, including deep nets. Because everything is trivial to reason about, there's nowhere for bugs, or zero day exploits, to hide. Oh.. and we'd do an open source data diode product as well.

Do you have any other examples where systolic arrays are suitable other than matrix multiplication? As far as I am aware, other problems require different systolic architectures. So I am curious whether you are talking about a general purpose architecture.

I'm talking about a Turing complete, general purpose architecture.[1] One with some seemingly stupid choices that turn out to work well. A cartesian grid of look up tables (LUTs) with latches, clocked in alternating phases. This slows things down, and makes it completely deterministic, and very easy to reason about. There are no race conditions to worry about. Like an excel spreadsheet, it's very easy to see all of the dependencies, and circular references aren't possible in the traditional sense, because of that delay.

I'm stuck in analysis paralysis... or I'd have more than an emulator[2] to show you. In theory, you can take any expression that can be broken down to a directed graph of binary logical expressions, and compile it into the "program" for the BitGrid. Because the grid is homogeneous, you can shift or rotate, or flip it to move the I/O around. The aforementioned dependency tracing makes it possible to prove the functionality conforms to the desired logical expression graph.

I need a kick in the pants to get the rest of this thing figured out. As near as I can tell, the only problems are my own writers block.

Non-genAI/LLM applications of ML are most exciting to me at the moment. Seems like the tooling and techniques are at a good point of proven but with creative prospects not yet explored, especially with generative siphoning off some of the hype. Worst case I’d learn some stats.

I have a feeling I would do something non-tech, I have a few ideas for FMCG items but I am not sure how to produce those at scale cause well its not my area of expertise, nor do I know about supply chain stuff. In terms of working capital, I don't have enough to produce it in meaningful numbers.

"FMCG stands for Fast-Moving Consumer Goods products sold quickly and relatively cheaply. Some examples of FMCG products include packaged foods, beverages, toiletries, cosmetics, cleaning supplies, and other low-cost household items."

The economy is bad, everything is expensive, and there is absolutely no social climate for emigrating within EU. That would be scenario equal to having my country invaded, or getting cancer, so death rather than thinking about opening a business. AI is only a topic in huge enterprises, I have yet to see anyone starting from zero and earning any money with it. There is lots of money incoming to real estate, physical g…

I think economic decline is regularly considered the best time to start a new business?

Good time to find people to hire and work hard to prepare for better times.

If I'm feeling conservative, I would open a self-storage facility. If I'm feeling energetic and risky, I would evaluate the commercial viability of radioisotope batteries.

I can help with the latter. The math can be quite sobering when you look at the potential regulatory burdens.

FOSS patent troll company. Agents would get employed by random companies that use linux/oss. Scan the licenses company uses, report back to HQ. First email would be from marketing "we can fix your issues", in case no or negative response, email from lawyers would follow.
